Settings resolution:

The resolution of the timing parameters (pulse width, delay, period) varies,

but is always better than 0.15% of (|set value| + 20 ns).

The amplitude resolution is < 0.1% of the maximum amplitude.

Settings accuracy:

Amplitude: Typically ± (3% of setting) ± (2% of maximum).

Delay, Period: Typically ± (3% of setting ) ± (5 ns)

Pulse width: Typically ± (3% of setting ) ± (2 ns), at maximum amplitude. As the

amplitude is reduced, the pulse width may shift ± 5 ns. For high-accuracy applications

requiring traceable calibration, verify the output with a calibrated oscilloscope

Connectors:

Out, Monitor: SMA. Trig, Sync, Gate: BNC

Optional accessory kit:
(attenuators and
terminators)

Add the suffix "-AK1" to the model number to include the recommended accessory kit. Consists of

three SMA, 18 GHz, 2 Watt attenuators (10, 20 & 30 dB) for use on the output, and two 50 Ohm, 1

GHz, 1 Watt feed-through terminators (one SMA, one BNC) for use on external trigger inputs.

Optional accessory kit:
(coaxial cables and
adapters)

Add the suffix "-AK8" to the model number to include the recommended accessory kit. Consists of

one 12-inch SMA-M/SMA-M PE-SR405FL coaxial cable, one 12-inch SMA-M/SMA-MRG-316

coaxial cable, one 36-inch SMA-M/SMA-M RG-316 coaxial cable, one 24-inch SMA-M/BNC-M RG-

316 coaxial cable, one 36-inch BNC-M/BNC-M RG58C/U coaxial cable, one SMA-F to BNC-M

adapter, one SMA-M to BNC-F adapter, one SMA-F to SMA-F adapter, and one SMA-F to solder

cup adapter

Power, Temperature:

100 - 240 V, 50 - 60 Hz. +5°C to +40°C.

Dimensions (H x W x D):

100 x 430 x 375 mm (3.9” x 17” x 14.8”)

1) -B suffix indicates IEEE-488.2 GPIB and RS-232 control of amplitude, pulse width, PRF and delay (See

http://www.avtechpulse.com/gpib

2) For operation at amplitudes of less than 20% of full-scale, best results will be obtained by setting the amplitude near full-scale and using external

attenuators on the output.

3) Indicate desired polarity by suffixing model number with -P or -N (i.e. positive or negative) or -PN for the dual polarity option

4) The -OS option adds an internal bias tee circuit to the output, allowing an externally-generated DC offset (±50V/250mA max) to be added the output

signal. The -OT option includes the -OS function, and adds the ability to generate a ±5V/100mA offset internally (controlled from the front panel, or by

computer command on -B units).

5) For monitor option add suffix -M.

6) A 50 Ohm load is required. Other loads may damage the instrument. Consult Avtech ([email protected]) if you need to drive other load

impedances.

7) The maximum output amplitude may decline by up to 25% when operating at PRFs higher than 20% of the maximum specified PRF, or the duty cycle

exceeds 5%, or the pulse width is less than 2 × (the specified rise time + the specified fall time).

8) These instruments are provided with a basic calibration checksheet, showing a selection of measured output parameters. These measurements are

performed with equipment that is calibrated on a regular basis by a third-party ISO/IEC 17025:2005 accredited calibration laboratory. However,

Avtech itself does not claim any accreditation. For applications requiring traceable performance, use a calibrated measurement system rather than

relying on the accuracy of the pulse generator settings.
