Measurement Summary

1.Connect the cable TV analyzer CAL OUT to the INPUT 75 Q and press the (PRESET) key.

2.Set the center frequency by pressing the following keys: L-1, 300 INIHz).

3.Set the span by pressing the following keys: m), 20 [MHz).

4.The calibration signal is 20 dB (two graticule divisions) below the top of the screen using these cable TV analyzer settings. If desired, adjust the reference level: press @ZiZG@ to activate the reference level, and use the knob or step keys to change the reference level.
