CONTROLS
1. INPUT signal connector: apply a 1-100 mv AC signal
between 10 cps and 20 Mc (5243L) or 10 cps and 50
Mc (5245L).
2. SENSITIVITY control: calibrated in millivolts, this
control determines the sensitivity of the Video
Amplifier and is adjusted to keep the signal output to
the Counter within limits acceptable to the Counter
input circuits as indicated on the OUTPUT LEVEL
meter.
3. OUTPUT LEVEL meter: meter monitors the level of
the Video Amplifier output to the Counter. When
meter indicates in green portion of scale, Video
Amplifier output to Counter is satisfactory.
4. OUTPUT 50
Ω
connector: when terminated in 50
ohms, the signal at this connector is identical in
frequency and amplitude to the Video Amplifier
output to the Counter.
