VM700A Option 01 (NTSC) & Option 11 (PAL) User Manual
Display and Graticule Intensity Control To change the intensity of the display or
the graticule, hold down the Display or Graticule button and rotate the control
knob.
Most VM700A measurements can only be done using either off-air (live) signals
or signals from a generator that have the appropriate test signals in the vertical
interval. Without the correct signal being applied, the displays contain no useful
information.
The bandwidth of the VM700A is 0 Hz (DC) to approximately 6.8 MHz.
The VM700A has three video loop-through inputs, one external sync loop-
through, and two RS-232C DTE ports on its rear panel (Figure 2-3). The audio
options (40 and 41) add appropriate connectors for application of the audio
signals to the option circuitry. The GPIB Interface (Option 48) add a standard
GPIB connector for remote control and GPIB hardcopy output.
Any video signal (of the appropriate format) may be connected to any video
input for normal operation. Certain options, Camera and Component being
examples, require connections to specific inputs for correct operation. Refer to
the option manual when connecting signals to make those option measurements.
