Impedance:
50 .
Ω
Duty Cycle:
Internal Trig-
gering
-50%.
External Trig-
gering
Determined by duty cycle of
triggering signal.
TRIGGER/GATE INPUT:
Sensitivity:
80 mV peak to peak to >10 MHz;
250 mV peak to peak to 50 MHz at
50 n input impedance.
Input Impedance: Internally selected, 50 n or 1 Mn
paralleled by -20 pF.
Maximum Input:
±5 V peak into 50 n, ±20 V peak
into 1 Mi.
Minimum Input
Pulse Width:
10 ns.
Trigger Level:
Polarity:
Front panel selectable, + or -slope.
Range: ±3 V.
TRIG'D GATED
LIGHT:
Flashing:
Input triggered at greater than
approximately a 10 Hz repetition
rate or following the input signal at
slower repetition rates.
On: (Logic True)
TRIG/GATE IN input potential
above TRIG/GATE LEVEL setting
with + SLOPE selected or below
TRIG/GATE LEVEL setting with -
SLOPE selected.
Off: (Logic False) TRIG/GATE IN input potential below
TRIG/GATE LEVEL with + SLOPE
selected or above TRIG/GATE
LEVEL with - SLOPE selected.
Synchronous Gate: Rate generator starts
synchronously with external gating
signal and completes the last output
pulse.
PULSE DELAY MODES:
Undelayed, delayed and paired. Paired pulse mode
limited to 25 MHz. Minimum pulse separation governed
by duration duty factor specification.
FIXED DELAYS:
Trigger Out to
Pulse Out:
-23 ns.
Gate Input to
Trigger Out:
-25 ns.
CONTROL ERROR LIGHT:
Steady On:
Indicates invalid operating mode.
Output is undefined.
Flashing:
Timing control settings selected do
not properly define the output pulse
because valid limits have been
exceeded.
Steady Off:
Indicates valid operation for most
control settings.
POWER REQUIREMENT:
Nominal:
40 Watts
Maximum:
45 Watts
POWER DISSIPATION:
Nominal:
25 Watts
Maximum:
28 Watts
