Display (typical parameters)
X, Y and Z outputs for auxiliary CRT displays exhibiting
< 75 nsec rise times for X, Y and < 30 nsec rise time for
Z (compatible with 1300 Series displays). X, Y:
1 volt full deflection; Z: 0 to 1 V intensity modulation,
–1 V blank. BLANK output (TTL level > 2.4 V for blanking)
compatible with most oscilloscopes.
Recorder (typical parameters)
Outputs to drive all current X-Y recorders
(using positive pencoils or TTL penlift input).
Horizontal sweep output (X axis): A voltage proportional to
the horizontal sweep of the frequency sweep generator
that ranges from 0 V for the left edge to +10 V for the
right edge. 1.7 kΩ output impedance.
Video output (Y axis): Detected video output (before A-D
conversion) proportional to vertical deflection of the
CRT trace. Output increases 100 mV/div from 0 to 1 V.
Output impedance ≤ 475 Ω.
Penlift output (Z axis; A blanking output, 15 V from 10 kΩ,
occurs during frequency sweep generator retrace; during
sweep, output is low at 0 V with 10 Ω output impedance
for a normal or unblanked trace (pen down).
LOWER LEFT and UPPER RIGHT push buttons calibrate the
recorder sweep and video outputs with 0,0 and 10,1 volts
respectively, for adjusting X-Y recorders. Pressing LOWER
LEFT with an GP-IB plotter connected will cause direct plot
of CRT information.
21.4 MHz IF
A 50 Ω, 21.4 MHz output related to the RF input to the analyzer.
