front-panel REF switch. The input signal may be composite sync, black
burst, or composite video.
5. CH-B. A bridging loop-through composite video input that is compensated
for 75
W
. The signal on this input is selected for display by the front-panel
INPUT switch.
6. CH-A. A bridging loop-through composite video input that is compensated
for 75
W
. The signal on this input is selected for display by the front-panel
INPUT switch.
Making a Signal Amplitude Measurement
The 1710J-Series Waveform Monitor can make both time and amplitude
measurements. The short procedure that follows allows you to locate the
blanking level, measure the sync amplitude, and measure the peak white level.
Timing measurements are more complex, they are discussed in the Reference
section of this manual.
1. Signal Input. Connect a 1 V color bar signal to one of the inputs of the
1710J-Series Waveform Monitor, preferably Ch-A, and terminate the
loop-through input with a 75
W
terminator. For the remainder of this
procedure this input signal will be referred to as “the signal.” This signal can
be from a generator or off of a program line.
2. Obtain a Display. Turn on the 1710J-Series Waveform Monitor POWER,
select CH A INPUT, FLAT FILTER, and INT REF. Set HORIZONTAL
SWEEP to 2 LINE and MAG off. Adjust the DISPLAY controls as
necessary for a usable display. Use the VERTICAL and HORIZONTAL
position controls to align the display with the graticule.
3. Check Instrument Vertical Calibration. Push and hold the REF switch
until the CAL indicator lights. Use the VERTICAL position control to align
the calibrator waveform with the graticule. See Figure 2–3.
