The AVOZ-DF models are high-voltage, high-current, high pulse repetition frequency (PRF) pulse generators. The high output voltages of the AVOZ-DF models permits the testing of laser diodes and laser diode arrays with relatively high forward voltage drops (VF). These models are voltage pulsers designed to drive 10 Ohm load impedances, and are provided with transmission line cables with a matched 10 Ohm total characteristic impedance (Z0), to minimize transmission lines reflections. An output module is included which provides a high-current low-inductance 10 Ohm series resistance internally, to allow low-impedance loads (such as laser diodes) to be driven directly. The AVOZ-DF3-B model can provide up to 200V of voltage and 20A of current. The maximum PRF is 25 kHz, and the pulse width can be adjusted from 20 to 200 ns. The rise and fall times are 5 ns or less, on a 20%-80% basis.

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 |
| Laser Diode Driver (Pulsed Voltage) | AVOZ-DF3-B |
$13733 |
Base model. Units with the -B suffix include the IEEE-488.2 GPIB and RS-232 computer control feature and a 2m/6ft GPIB cable. |
| Polarity Options | |||
| Positive output polarity |
-P |
0 |
A polarity must be specified. |
| Negative output polarity |
-N |
0 |
A polarity must be specified. |
| 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. |
| Miscellaneous Options | |||
| Rack Mount Kit | -R5 | $322 | Option. For 17-inch-wide models only. Check datasheet for instrument dimensions. (All -B units are 17 inches). |
| Extra GPIB cable, 1 meter | -X1 | $53 | Option. |
| Extra GPIB cable, 2 meters | -X2 | $75 | Option. |
| Extra GPIB cable, 4 meters | -X4 | $97 | Option. |
| Replace 1m/36"-long cables with 3m/118"-long cables | -XC3 | $755 | Option. |
| AC Power Cords | |||
| Power cord for United Kingdom, Hong Kong, Singapore, Malaysia | -AC00 | $0 | Option. BS 1363, 230V, 50 Hz. |
| Power cord for Australia, New Zealand | -AC01 | $0 | Option. AS 3112:2000, 230-240V, 50 Hz. |
| Power cord for Continental Europe, Korea, Indonesia, Russia | -AC02 | $0 | Option. CEE 7/7 Schuko, 230V, 50 Hz. |

| Power cord for Israel | -AC19 | $0 | Option. SI 32, 220V, 50 Hz. |
| Power cord for China | -AC22 | $0 | Option. GB 1002-1, 220V, 50 Hz. |
| 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.

Prices - International
Customers in Austria, China, The Czech and Slovak Republics, France, Germany, India, Japan, Korea, Switzerland, Taiwan and Turkey should contact their local representative for pricing. International prices will be somewhat higher than the USA/Canada pricing shown above, depending on local documentation requirements, customs and shipping procedures, and other regulatory issues (for example, the European WEEE directive).
Customers in other countries should contact our Canadian headquarters directly for pricing. Avtech can ship internationally by FedEx (preferred), UPS, DHL, or Bax Global.
