for details.
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:
Typically ± 5% (plus ±2 V or ± 2 ns) after 10 minute warmup.
For pulse widths below ~10 ns, the amplitude accuracy degrades to ± 10% ± 10 V.
For high-accuracy applications requiring traceable calibration,
verify the output parameters with a calibrated oscilloscope.
DC offset or
bias insertion:
Optional
6
. Apply required DC offset or bias in the range of
± 50 Volts (250 mA max) to back panel solder terminal.
Propagation delay:
≤ 100 ns (Ext trig in to pulse out)
Jitter:
± 35ps ± 0.015% of sync delay (Ext trig in to pulse out)
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.
Variable delay:
Sync to Out: 0 to 1.0 seconds, for all trigger modes (including external trigger).
Sync output
+3 Volts, 100 ns, will drive 50 Ohm loads
Connectors:
Out: SMA, Trig, Sync, Gate: BNC
Power requirement:
100 - 240 Volts, 50 - 60 Hz
Dimensions:
H x W x D: 100 × 430 × 375 mm (3.9 × 17 × 14.8”)
Rack-mount kit:
Optional. To specify, add the -R5 suffix to the model number.
Temperature range:
+5°C to +40°C
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 analog electronic control (0 to +10V) of amplitude, suffix the model number with -EA. Includes standard front-panel controls. Not available on
AVIR-4 models.
3) For operation at amplitudes of less than 10% of full-scale, best results will be obtained by setting the amplitude near full-scale and using external
attenuators on the output.
4) Indicate desired polarity by suffixing model number with -P or -N (i.e. positive or negative) or -PN for dual polarity option. Polarity reversal is achieved
by means of a two-position switch.
5) Add the suffix -VXI to the model number to specify the Ethernet port.
6) For externally-applied DC offset option suffix model number with -OS. For internally-generated DC offset option (0 to ±5V) add suffix -OT.
7) The maximum amplitude decreases by 15% for repetition rates above 30 kHz. The maximum amplitude also decreases by an additional 15% for
pulse widths below 3 ns.
8) A 50 Ohm load is required. Other loads may damage the instrument. Consult Avtech ([email protected]) if you need to drive other load
impedances.
