8CONTROL functions access menus that allow you to adjust the resolution bandwidth, adjust the sweep time, store and manipulate trace data, and control the instrument display.

9MARKER functions control the markers, read out frequencies and amplitudes along the cable TV-analyzer trace, automatically locate the signals of highest amplitude, and keep a signal at the marker position in the center of the screen.

10WINDOWS keys, turn on the windows display mode. They allow switching between windows and control the zone span and location.

11 DATA keys, STEP keys, and knob allow you to change the numeric value of an active function.

12 INPUT 75 D is the signal input for the cable TV analyzer.

Excessive signal input will damage the cable TV analyzer input attenuator and input mixer. Use extreme caution when using the cable TV analyzer around high-power RF sources and transmitters. The maximum input power that the cable TV analyzer can tolerate appears on the front panel and should not be exceeded.

Excessive dc voltage can also damage the input attenuator. For your particular instrument, note the maximum dc voltage that should not be exceeded on the cable TV analyzer front panel (beneath the INPUT 75 62 connector).

13PROBE PWR provides power for high-impedance ac probes or other accessories.

14CAL OUT provides a calibration signal of 300 MHz at 29 dBmV.

15VOL-INTEN The VOL-INTEN knob changes the brightness of the display and the volume of the internal speaker. The inside part of the knob adjusts the intensity while the outside part adjusts the volume.

16TV IN Provides the input for the built-in Television-tuner, Option 107.
