j. Set the spectrum analyzer cursor to 30 MHz and then set the marker to
30 MHz.
k. Reconnect the cable to the RF Bridge.
l. Note the Reference Level Readout.
m. Adjust the spectrum analyzer External Attenuation Amplitude by the
amount noted in step l. Note: The Reference Level Readout should now
be 0.00 dBm.
n. Connect the precision high-frequency terminator to the Device Under
Test connector on the RF Bridge.
o. Check that the frequency response from 0 MHz to 30 MHz is >35 dBm.
p. Return the frequency marker to 30 MHz if it was moved.
q. Remove the precision high-frequency terminator from the RF Bridge.
r. Connect the Device Under Test connector on the RF Bridge to the
CH 1A INPUT on the 1735 HD through a male-to-male BNC adapter.
Terminate the CH 1A loop-through with the precision high-frequency
terminator used in step n.
s. Select CH 1, CH 2, and CH 3 INPUTs, both A and B INPUTs (all
INPUT Channel LEDs should be on), and ONE LINE Sweep.
t. Check for a Reference Level Readout on the spectrum analyzer of
>35 dBm.
u. On the 1735 HD, switch between GND Off and On and check that the
Reference Level Readout on the spectrum analyzer does not change by
more than
±
2 dBm.
v. Move the RF Bridge and loop-through precision high-frequency
terminator to each of the video INPUT channels, and repeat steps t. and
u. for each of them.
w. Move the RF Bridge and loop-through precision high-frequency
terminator to the EXT REF Input.
x. Check for a Reference Level Readout on the spectrum analyzer of
>33 dBm.
y. On the 1735 HD, switch between GND Off and On and check that the
Reference Level Readout on the spectrum analyzer does not change by
more than
±
2 dBm.
z. Move the RF Bridge to the PIX MON OUT connector, with the
1735 HD POWER ON.
