SPECIFICATIONS
Model1:AV-1015-B
Amplitude2,6, with ZOUT = 2Ω:
with ZOUT = 50Ω:
≤5 to 50 V
≤1 to 25 V
Pulse width, PW (FWHM)3:20 ns to 10 ms
Rise time (20%-80%)4:≤ 10 ns
Fall time (80%-20%)4:≤ 10 ns
Pulse repetition frequency, PRF: 1 Hz to 10 MHz
Maximum duty cycle: 25% into 50Ω loads
50% into >200Ω8
Output impedance (ZOUT)5:≈ 2 Ω or 50 Ω, switchable
Required load impedance: ≥ 50 Ω
Output polarity: Positive or negative, switchable
Leading edge overshoot (into a
non-inductive 50 Ω load):
≤ 8% of maximum rated amplitude for all amplitudes. Typically < 3% at maximum amplitude.
Settles to ±3% of stable amplitude within 60 ns.
Typical pulse-top droop: dV/dt ≈ IOUT÷4000uF
Double pulse mode spacing: 1 us to 1 second (measured between the two leading edges of the pulse doublet). Must
not exceed one-half of the period. There must be at least (PW + 100 ns) of “dead time”
(no pulsing) between the trailing edge of the first pulse and the leading edge of the second
pulse. For instance, if the pulse width is 1 us, the programmed delay between leading edges
must be greater than 1 us (the pulse width) + 1.1 us (the minimum dead time) = 2.1 us,
and the period must be greater than 4.2 us.
Sync output: +3V, >30ns, to ≥50Ω
Gated operation: TTL, synchronous or asynchronous, active high or low, switchable.
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 output: 0 to ±1.0 seconds, for all trigger modes (including external trigger).
Propagation delay: ≤ 150 ns (Ext trig in to pulse out)
Jitter: ≤ ± 35ps ± 0.015% of sync delay (sync out to pulse out)
GPIB and RS-232 control1 :Yes, standard feature on all -B units.
Ethernet port, for remote control
using VXI-11.3, ssh, telnet, &
web:
Included. Recommended as a modern alternative to GPIB / RS-232.

LabView drivers: Available for download at http://www.avtechpulse.com/labview.
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, at low duty cycles .
For high-accuracy applications requiring traceable calibration,
verify the output parameters with a calibrated oscilloscope9.
Output protection: The output is protected against short circuits, open circuits, and high duty cycle
Connectors, BNC female
Power requirements: 100 - 240 Volts, 50 - 60 Hz
Dimensions: 100 mm x 430 mm x 3 5 mm (3.9” x 1 ” x 14.8”)
Chassis material, weight: Anodized aluminum with blue-gray plastic trim. ≤ 10 kg / 22 lbs.
Designed & assembled in North America.
Temperature range: +5°C to +40°C
Optional rack-mount kit: Add the suffix “-R5” to the model number to include 19” rack mount kit
1) -B suffix indicates IEEE-488.2 GPIB and RS-232 control of amplitude and frequency. See http://www.avtechpulse.com/ gpib for details.
2) The output amplitude may also be controlled by applying 0 to +10 V DC to a rear-panel BNC connector.
3) 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 (PWIN =
PWOUT mode).
4) Valid into a 50 Ohm load.
5) This is the internal resistance in series with the output. It is not the load resistance.
6) The output can be set at lower values, but the overshoot may become significant relative to the pulse amplitude at low amplitudes.
