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 ± 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.
Propagation delay:
≤ 100 ns (Ext trig in to pulse out)
Jitter:
± 100 ps ± 0.03% of sync delay, Ext trig in to pulse out
DC offset or bias insertion:
Option available. Apply required DC offset or bias in the range of ± 50 Volts,
(250 mA max) to back panel solder terminal. See note 7.
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:
0 to 1.0 seconds, for all trigger modes (including external trigger).
Sync output:
> +3 Volts, > 50 ns, will drive 50 Ohm loads
Gate input:
Synchronous or asynchronous, active high or low, switchable. Suppresses triggering when active.
Connectors:
Out, Trig, Sync, Gate: BNC
Dimensions:
100 mm x 430 mm x 375 mm (3.9” x 17” x 14.8”)
Power requirements:
100 - 240 Volts, 50 - 60 Hz
Chassis material:
Cast aluminum frame & handles, blue vinyl on aluminum cover plates
Mounting:
Any
Temperature range:
+5°C to +40°C
1)
-C suffix indicates stand-alone lab instrument with internal clock and line powering. No suffix indicates miniature module requiring DC power and
external trigger. (See
http://www.avtechpulse.com/formats
for details of the four basic instrument formats).
2)
-B suffix indicates IEEE-488.2 GPIB and RS-232 control of amplitude, pulse width, PRF and delay (See
http://www.avtechpulse.com/gpib
).
3) For analog electronic control (0 to +10V) of the amplitude, suffix model number with -EA. Electronic control units also include standard front-panel
controls.
4) 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.
5) For 10-turn dial control of pulse width (or amplitude) suffix model number with -PWT (or -AT). For -C units only.
6) Indicate desired polarity by suffixing model No. by -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 on -C units and by keypad control on -B units.
7) For DC offset option suffix model number with -OS.
8) The instrument may be damaged by load impedances outside this range.
9) Add the suffix -VXI to the model number to specify the Ethernet port.
