1735 HD High Definition Waveform Monitor
20. Check X1 and X5 Flat Response
a. Connect the leveled sine wave generator output, through a 50
W
precision cable and a 50-to-75
W
minimum loss attenuator, to the
1735 HD CH 1A INPUT.
b. Connect the peak-to-peak detector head to the remaining side of the
1735 HD CH 1A INPUT. Connect the peak-to-peak detector head to the
+ (plus) input of the peak-to-peak detector. Connect the output of the
peak-to-peak detector, through a BNC-to-dual banana plug adapter, to
the digital voltmeter (DVM). Enable the peak-to-peak de (plus)
input.
c.
Select CH 1A INPUT, CH 1 REF, FLAT Filter, and ONE LINE Sweep
on the 1735 HD.
d. Set the leveled sine wave generator Frequency Range to 50 kHz and
adjust its Output Amplitude for a 700 mV display on the 1735 HD.
e.
Set the DVM range for three-place accuracy and adjust the peak-to-peak
de level for a reading as close to zero as possible. Note the
reference reading.
NOTE
. To calculate the deviation from flatness, set the leveled sine wave
generator to the frequency being checked and adjust the output amplitude to
obtain the same level on screen as seen at the 50 kHz reference. Note the DVM
reading at the frequency being checked and subtract it from the DVM reading
observed at the 50 kHz reference.
f.
Use the leveled sine wave generator Frequency controls to provide all
frequencies from 250 kHz to 30 MHz.
g. Check frequency response for
±
2% or 14 mV from 250 kHz to 30 MHz.
Note: If this check does not pass, then repeat Step 19.
h. Repeat steps a. through g. for CH 2A, CH 3A, CH 1B, CH 2B, and
CH 3B.
i.
Select the 1735 HD X5 Gain.
j.
Set the leveled sine wave generator to 50 kHz and adjust its Output
Amplitude for a 700 mV display.
k. Use the leveled sine wave generator frequency controls to provide all
frequencies from 250 kHz to 30 MHz.
l.
Check frequency response for
±
2% or 14 mV from 250 kHz to 30 MHz.
m. Repeat steps j. through l. for CH 1A, CH 2A, CH 3A, CH 1B, and CH
2B.
