Performance Verification
1735 HD High Definition Waveform Monitor
5–19
g. Change the PG506A connection and 1735 HD channel selection to each
INPUT channel in turn, repeating step f. for all remaining channels:
CH 2A, CH 3A, CH1B, CH 2B, and CH 3B.
20. Check X5 Transient Response
Requirement: Transient response for a 140 mV, 150 ns rise-time step:
preshoot, overshoot, and ringing 1% or less.
a. Select X5 Gain on the 1735 HD.
b. Set the PG506A controls for a 700 mV output.
c. Use the VERTICAL Position controls to position the display between
the 0 V and 700 mV graticule lines. Use the HORIZONTAL Position
control to view the positive-going transition.
d. Check for less than 1% preshoot, overshoot, and ringing.
e. Change the PG506A connection and 1735 HD channel selection to each
INPUT channel in turn, repeating step d. for all remaining channels:
CH 1B, CH 2B, CH1A, CH 2A, and CH 3A.
f. Disconnect all INPUT signals and terminations from the 1735 HD.
21. Check Square Wave Tilt
Requirement: Field Rate Square Wave or Vertical Window, 1% or less tilt.
a. Connect the TSG 1001 G/Y output to the 1735 HD CH 1A INPUT.
Terminate the loop-through in 75
W
.
b. Select a Field-Rate Square Wave signal with a 700 mV bar amplitude.
c. Select CH 1A INPUT, FLAT Filter, X1 Gain, and TWO FIELD Sweep
on the 1735 HD.
d. Check that there is 1% or less tilt on the bar top, as viewed on the
1735 HD.
22. Check Noise Filter Response
Requirement: Response at 15 kHz does not vary between FLAT and FILTER
by more than 1% when NOISE Filter is selected. >20 dB of attenuation at
20 MHz.
a. Select EXT REF and ONE LINE Sweep on the 1735 HD.
b. Connect a precision 50
W
cable and 50-to-75
W
minimum loss attenuator
from the function generator output to the CH 1A INPUT.
c. Set the function generator for a 15 kHz sine wave. Adjust the amplitude
for a 700 mV display on the 1735 HD.
