1710J-Series Waveform Monitors
Using 50 kHz as the reference the requirements are
H
X1 gain 250 kHz to 6 MHz within 2%
H
X5 gain 250 kHz to 6 MHz within 5%
1. Connect a 50
Ω
precision cable and 50 to 75
Ω
minimum loss pad from the
leveled sine wave generator to the CH A input. Terminate the remaining side
of the loop-through input with a 75
Ω
end-line terminator. See Figure 6–4.

2. Select EXT REF.
3. Set the leveled sine wave generator frequency range to 50 kHz and set the
output amplitude for a 100 IRE (0.7 V) display amplitude.
4. Check the flat response using the 50 kHz response as a reference. While
changing the frequency of the sine wave generator, check that the response is
within
±
2% from 250 kHz to 6 MHz.
5. Change the VERTICAL GAIN to X5.
6. Set the leveled sine wave generator to 50 kHz and set the output amplitude
for a 100 IRE (0.7 V) display amplitude.
7. Check flat response using the 50 kHz response as a reference. Check that the
amplitude is 100 IRE (0.7 V)
±
5% from 250 kHz to 6 MHz.
8. Move the 75
W
coaxial cable that comes from the leveled sine wave
generator output to CH B. Terminate the remaining side of the loop-through
input with a 75
W
end-line terminator.
9. Select CH B input.
10. Check flat response using the 50 kHz response as a reference. Check that the
amplitude is 100 IRE (0.7 V)
±
5% from 250 kHz to 6 MHz.
