The rise time is less than 100 ps, and the fall time is less than 200 ps. Models without the “-W” suffix have a pulse width variable from 2 to 50 ns. Models with the “-W” suffix have a pulse width variable from 20 to 500 ns. Instruments with the "-P" model suffix can generate 0 to +10V, whereas instruments with the "-N" model suffix can generate 0 to -10V. Instruments with the "-P-PN" suffix generate 0 to +10V at the main outp ut, and are supplied with an inverting transformer that can be installed on the out put to generate a negative signal. Instruments with the "-N-PN" suffix generate 0 to -10V at the main outp ut, and are supplied with an inverting transformer that can be installed on the out put to generate a positive signal. The output is designed to drive 50Ω loads. (A 50Ω load is required for proper operation.) The output is AC-coupled. This instrument is intended for use in research, development, test and calibration laboratories by qualified personnel. __________________________________________________________________ 6 AVAILABLE OPTIONS The AVP-AV-2-C is available with several options: -EA Option: the output amplitude can be controlled by an externally gen erated 0 to +10V analog control voltage. -ECL Option: the input trigger levels are ECL, rather than TTL. -EO Option: the output offset can be controlled by an externally genera ted 0 to +10V analog control voltage. -EW Option: the output pulse width can be controlled by an externally g enerated 0 to +10V analog control voltage. -M Option: a monitor output is provided. -OS Option: an externally generated DC offset can be added to the outpu t. -OT Option: an internally generated DC offset, controlled by a front-pa nel dial, can be added to the output. -W Option: the pulse width is variable from 20 to 500 ns, instead of th e standard 2 to 50 ns. __________________________________________________________________ 7 SPECIFICATIONS Model: AVP-AV-2-C1 Amplitude3,4,8: (50 Ohm load) 0 - 10 Volts Pulse width (FWHM)3: 2 - 50 ns std.

P OWER Switch . This is the main power switch. When turning the instrum ent on, there may be a delay of several seconds before the instrument appears t o respond. 2. O VERLOAD Indicator . When the instrument is powered, this indicator is normally green, indicating normal operation. If this indicator is yellow, an int ernal automatic overload protection circuit has been tripped. If the unit is overloaded (by operating at an exceedingly high duty cycle or by operating into a very low impedance), the protective circuit will disable the output of the instr ument and turn the indicator light yellow. The light will stay yellow (i.e. outpu t disabled) for about 5 seconds after which the instrument will attempt to re-enable th e output (i.e. light green) for about 1 second. If the overload condition persis ts, the output will be disabled again (i.e. light yellow) for another 5 seconds. If th e overload condition has been removed, the instrument will resume normal operation . This overload indicator may flash yellow briefly at start-up. This is n ot a cause for concern. 3. P RF Range Switch . This switch sets the pulse repetition frequency (PR F) range of the internal oscillator. The marked value of each position is the up per limit of the 10:1 range, approximately. The vernier dial directly below the swit ch varies the PRF within the set range. If this switched is set to the “EXT” position, the instrument is trigge red by a signal applied to the TRIG connector, rather than by the internal oscillator. 4. T RIG Connector . When the PRF Range Switch is set to “EXT”, the instru ment is triggered by a TTL pulse applied to this connector. The pulse must be a t least 50 ns wide. When the PRF Range Switch is set to one of the four internal oscillator ranges, __________________________________________________________________ 16 this connector is an output, which supplies a 2V, 200 ns wide pulse for each trigger event. This output may be used to trigger oscilloscopes or othe r equipment. 5. D elay Controls . When the PRF Range Switch is set to one of the four i nternal oscillator ranges, the main output is advanced or delayed relative to t he TRIG output pulse (item 4). The delay is variable up to 200 ns, approximatel y, using the DELAY and DELAY FINE dials. 6. A dvance/Delay Switch . When the PRF Range Switch is set to one of the four internal oscillator ranges, this switch determines whether the TRIG out put precedes the main output (ADVANCE mode), or whether the TRIG output occ ur after the main output (DELAY mode). 7. P ulse Width Control . This dial controls the pulse width. 8. A mplitude Control . This dial controls the amplitude. 9. O UT Connector . This SMA connector provides the main output. This outp ut requires a 50Ω load to function properly. __________________________________________________________________ 17 REAR PANEL CONTROLS 4 9 6 5 1 3 MON OS GND INT EXT A PW OFFSET AMP ON OFF OFFSET OUT 8 7 2 1. A C POWER INPUT . An IEC-320 C14 three-pronged recessed male socket is provided on the back panel for AC power connection to the instrument. O ne end of the detachable power cord that is supplied with the instrument plugs in to this socket. 2. A C FUSE DRAWER . The two fuses that protect the AC input are located i n this drawer. Please see the “FUSES” section of this manual for more informat ion. 3. D C FUSES . These two fuses protect the internal DC power supplies. Ple ase see the “FUSES” sections of this manual for more information. 4. O S INPUT CONNECTOR . (Present on units with -OS option only.) A DC off set in the range of ±50V (250 mA max) may be applied to this solder terminal. The DC offset will appear on the output. When this feature is not used, the OS input should be connected to ground (using the adjacent GND connector). This is espe cially important when driving loads containing a diode. 5. G ND CONNECTOR . (Present on units with -OS option only.) This solder t erminal is connected to ground. It may be used to ground the OS input connector. 6. M ON OUTPUT CONNECTOR . (Present on units with -M option only.) This SM A connector output provides a 20 dB attenuated coincident replica of main output, for monitoring purposes. 7. O FFSET ON/OFF SWITCH & OUTPUT. (Present on units with -EO or -OT opti ons only). This switch enables the offset feature when it is set to “ON”. W hen it is set to “OFF”, no offset is added to the output. The internally generated offse t is available at the “OFFSET OUT” BNC connector, for monitoring purposes. To add an o ffset to inverted pulses on units with the dual polarity option (-PN), connect t his terminal to __________________________________________________________________ 18 the DC terminal of the inverting transformer (see the “POLARITY INVERSI ON” sections in this manual for further details). 8. A MP SWITCH & INPUT . (Present on units with -EA option only.) To contr ol the output amplitude with an external voltage, set the rear-panel switch to the “EXT” position and apply 0 to +10V to the adjacent connector (R ≥ 10kΩ). IN 9. P W SWITCH & INPUT . (Present on units with -EW option only.) To contro l the output pulse width with an external voltage, set the rear-panel switch to the “EXT” position and apply 0 to +10V to the adjacent connector (R ≥ 10kΩ). IN __________________________________________________________________ 19 GENERAL INFORMATION BASIC TEST ARRANGEMENT The AVP-AV-2-C should be tested with a sampling oscilloscope with a ban dwidth of at least 10 GHz to properly observe the high-speed waveform. (The cables a nd attenuators must also have a bandwidth of at least 10 GHz.) A typical t est arrangement is shown below: AVTECH SAMPLING PULSER OSCILLOSCOPE BW > 10 GHz MAIN OUTPUT 50 OHM INPUT CONNECTOR 40 dB AC ATTENUATOR POWER TRIG TRIG CONNECTOR CONNECTOR ALL CABLES: 50 OHM COAXIAL The attenuators are required to prevent damage to the sampling oscillos cope. A 40 dB attenuator with sufficient voltage rating should be used on the main ou tput. BASIC PULSE CONTROL This instrument can be triggered by its own internal clock or by an ext ernal TTL trigger signal. When triggered internally, two mainframe output channels respon d to the trigger: OUT and SYNC.  OUT. This is the main output. The maximum output voltage is 10V.  TRIG. The TRIG pulse is a fixed-width TTL-level reference pulse used to trigger oscilloscopes or other measurement systems. The TRIG output precedes the main output. These pulses are illustrated below: __________________________________________________________________ 20 200 ns, FIXED TRIG (generated by the 2V, FIXED internal oscillator) DELAY PULSE WIDTH AMPLITUDE, VARIABLE MAIN OUTPUT When triggered externally, the TRIG connector acts as an input. The del ay controls do not function in this mode. This illustrated below: > 50 ns TRIG TTL LEVELS (external input) (0V and 3V-5V) PROPAGATION DELAY (FIXED) PULSE WIDTH MAIN OUTPUT AMPLITUDE, VARIABLE AMPLITUDE INTERACTION Some properties of the output pulse may change as a function of the amp litude setting. For some demanding applications, it may be desirable to use a combinati on of external attenuators and the amplitude pot to achieve the desired output amplitu de. POLARITY CONTROL Instruments with the "-PN" suffix have two output connectors, only one of which is active at a time. One provides positive pulses, the other provides negative pu lses. A front panel switch determines which output is active. __________________________________________________________________ 21 MINIMIZING WAVEFORM DISTORTIONS U SE 50 Ω TRANSMISSION LINES AND LOADS Connect the load to the pulse generator with 50Ω transmission lines (e. g. RG-58 or RG- 174 cable). This instrument requires a 50Ω load for proper operation. It will not p roperly drive a high-impedance load. The output stage will be damaged if it is operated into an open circuit (or any other high impedance). Failures due to improper output loading are not covered by the warranty. USE LOW-INDUCTANCE LOADS Lenz’s Law predicts that for an inductive voltage spike will be generat ed when the current through an inductance changes. Specifically, VSPIKE = L × dILOA D/dt, where L is the inductance, ILOAD is the load current change, and t is time. For th is reason, it is important to keep any parasitic in the load low. This means keeping wir ing short, and using low inductance components. In particular, wire-wound resistors sh ould be avoided. PREVENTING DAMAGE The AVP-AV-2-C may fail if triggered at a PRF greater than 50 kHz. This unit is designed to operate into a load impedance of 50 Ohms and t he output stage will be damaged if it is operated into an open circuit (or any other hi gh impedance). Failures due to improper output loading are not covered by the warranty . The lifetime of the switching elements in the pulse generator module is proportional to the running time of the instrument. For this reason the prime power to the instrument should be turned off when the instrument is not in use. __________________________________________________________________ 22 MECHANICAL INFORMATION TOP COVER REMOVAL If necessary, the interior of the instrument may be accessed by removin g the four Phillips screws on the top panel. With the four screws removed, the top cover may be slid back (and off). Always disconnect the power cord before opening the instrument. There are no user-adjustable internal circuits.
