The AVR-8A-B is a general-purpose 1000V pulse generator, with a wide pulse width range of 200 ns to 200 us, rise and fall times of 50 ns, and a maximum repetition rate of 1 kHz. This model can drive loads of 50 Ohms or higher. When used to drive a series combination of 50 Ohms and a laser diode, it can deliver up to 20 Amps to the diode. Models in the AVR series may be suitable for replacing obsolete pulse generators from the former Velonex Corporation in many applications.

Prices - USA and Canada
Standard US/Canada prices are listed below. We can also provide you with a formal quote.
| Base Model | P/N | Price | Notes |
| High Voltage Pulser | AVR-8A-B |
$16761 |
Base model. Units with the -B suffix include the IEEE-488.2 GPIB, VXI, and RS-232 computer control feature, and a 2m/6ft GPIB cable. |
| Production status: last-time order date is January 31, 2025. | |||
| Polarity Options | |||
| Positive output polarity |
-P |
0 |
A polarity must be specified. |
| Negative output polarity |
-N |
0 |
A polarity must be specified. |
| Dual polarity | -PN | $5405 | Option. |
| Alternative Output Connectors | |||
| HN output connector | -HN | $252 | Option. Replaces standard output connector. |
| MHV output connector | -MHV | $252 | Option. Replaces standard output connector. |
| N output connector | -NC | $252 | Option. Replaces standard output connector. |
| Connectivity Options | |||
| Ethernet port, for remote control using VXI-11.3, ssh, telnet, and web | -VXI | $0 | Option. Standard feature for orders after Jan 14, 2019 - it is no longer necessary to specify this option. Adds a rear-panel Ethernet connector, allowing the instrument to be remotely controlled using the VXI-11.3, ssh (secure shell), telnet, and http (web) protocols. In particular, the VXI-11.3 features allows software like LabView to control an instrument using standard VISA communications drivers and network cabling, instead of using old-style GPIB cabling. (This eliminates the need for a GPIB controller card and its proprietary drivers.). |
| Extra Documentation | |||
| Provide a Certificate of Conformance | -CC1 | $106 | Option. |
| Provide an installed IUID-format label | -ID1 | $106 | Option. Label only. Does not include data registration. Records the manufacturer CAGE code, the instrument serial number, and the model number. |
| Increased Average Power and Duty Cycle | |||
| High Power | -XP1 | $3134 | Option. |
| Extra High Power | -XP2 | $6162 | Option. Not available on dual-polarity models, due to space limitations. |
| Miscellaneous Options | |||
| Quick-discharge circuit for higher throughput | -QD | $3134 | Option. |
| Rack Mount Kit | -R5 | $322 | Option. For 17-inch-wide models only. Check datasheet for instrument dimensions. (All -B units are 17 inches). |
| Safety interlock | -SIL | $898 | Option. This option adds a safety lock circuit on a rear-panel BNC connector. The signal pin of this safety lock BNC connector must be shorted to chassis ground by the user’s circuitry (the short must be capable of carrying 5 mA of current from an internal +5V/1kΩ DC source), otherwise the output will be switched off automatically. The connector shield is connected to chassis ground. |
| Extra GPIB cable, 1 meter | -X1 | $53 | Option. |
| Extra GPIB cable, 2 meters | -X2 | $75 | Option. |
| Extra GPIB cable, 4 meters | -X4 | $97 | Option. |

| Shipping Case | |||
| ATA shipping case | -ATA3 | $1398 | Option. Ships the instrument in a heavy-duty ATA-style transport case, instead of the normal cardboard box. It can also serve as a storage case. This option is recommended for shipments outside of North America and Europe, and is mandatory when using a freight-forwarder or when shipping by any method other than FedEx/UPS. It is strongly recommended for all shipments to China. Pelican model 1690 for full-rack-width (17 inch / 430 mm) units, including all -B units. Pelican model 1610 for half-rack-width (8.5 inch / 215 mm) units. This option increases the shipping weight by 45 lbs / 20 kg (1690) or 24 lbs / 11 kg (1610). |
| Shipping Method | |||
| Ship to USA or Canada, on Avtech FedEx Priority account | $0 | Included in base price. | |
| Ship globally, on customer FedEx or UPS account | $0 | Excludes Austria, China, The Czech and Slovak Republics, Germany, India, Japan, Korea, Switzerland, Taiwan and Turkey. Consult your local representative for pricing. | |
| Ship globally, on Avtech FedEx Priority account | Contact Avtech for pricing. | Excludes the above countries. | |
| Ship globally, using a customer-specified freight forwarder | Contact Avtech for pricing. | Excludes the above countries. Not recommended. Due to the increased likelihood of shipping damage, the -ATA3 option (heavy-duty ATA shipping case) is mandatory for -PS, -C, and -B models. | |
These prices are in U.S. dollars, and apply only to orders placed directly with Avtech from the United States and Canada. Reseller prices may be higher. A 5% academic discount is available for North American universities. Orders are non-cancellable, non-returnable.
