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 (into 50Ω):
Typically ± 3% (plus ±1V or ± 2 ns) after 10 minute warmup. For high-accuracy applications
requiring traceable calibration, verify the output parameters with a calibrated oscilloscope 6 .
Propagation delay: ≤ 200 ns (Ext trig in to pulse out)
Jitter (Ext trig in to pulse out): ± 100 ps ± 0.03% of sync delay
Trigger modes:
Internal trigger, external trigger (TTL level pulse, > 10 ns, 1 kΩ input impedance),
front-panel “Single Pulse” pushbutton, or single pulse trigger via computer command.
In the external trigger mode, the pulse width may be set by the instrument,
or it may be set to track the input pulse width.
Variable delay:
Sync to main out: 0 to 1.0 seconds, for all trigger modes (including external trigger).
Sync output: > +3 Volts, > 50 ns, will drive 50 Ohm loads
Gated operation: Synchronous or asynchronous, active high or low, switchable. Suppresses triggering when active.
Connectors: OUT: SHV 8,9 . Trig, Sync, Gate: BNC
Power requirements: 100 - 240 Volts, 50 - 60 Hz
Dimensions (H x W x D): 100 mm x 430 mm x 375 mm (3.9” x 17” x 14.8”)
Chassis material: cast aluminum frame and handles, blue vinyl on aluminum cover plates
Temperature range: +5°C to +40°C
1) The output pulse width may also be controlled externally by applying a TTL-level trigger of the desired width to a rear-panel BNC connector (PW
IN
=
PW
OUT
mode).
2) The output amplitude is controlled by internal high-voltage DC power supplies. When the amplitude setting is reduced, the high voltage decays in an
exponential fashion, with the typical time constant noted in this specification.
3) More frequent discharges will cause the instrument to overheat, and may cause damage.
4) The output amplitude is controlled by internal high-voltage DC power supplies. This is the time required for the power supplies to rise from 5% to
95% of their full value in response to a change in settings from zero to the maximum setting.
5) Valid for 200 Ohm loads. The droop will be proportionally higher into lower resistance loads.
6) 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.
7) The maximum average output power is only obtainable at maximum amplitude.
