4.2.2. Displaying the RF Power Input Level

The 7703DA4/8-RF detects the input RF power input level and displays this on the four-digit card edge

display. By entering the MON menu and then selecting IN from the next menu level and INPL from the

next level, the input RF power level in dBm will be displayed.

To adjust the gain, enter the menu setting SET / GAIN. Here a range of values will be given for the gain

settings. The current gain is displayed on the screen and does not require pressing the pushbutton to

select.

The input RF level thresholds can be set by entering into the menu structure SET / IN / UPPR and SET /

IN / LWR.

Toggling the switch will move through a range of values in 1dBm increments. Hitting the

pushbutton will select the displayed value. In manual gain mode, the input threshold levels can be

selected but the output level thresholds are determined by the gain setting and the input threshold levels.

The output threshold levels are determined as follows:

OUTPUT UPPER THRESHOLD=INPUT UPPER THRESHOLD + GAIN SETTING

OUTPUT LOWER THRESHOLD=INPUT LOWER THRESHOLD + GAIN SETTING

For example, if the gain is set to +10dB, and the input lower threshold is –20dBm and the input upper

threshold is –5dBm, then the output thresholds will be:

OUTPUT UPPER THRESHOLD = -5dBm + 10dB = +5dBm

OUTPUT LOWER THRESHOLD = -20dBm + 10dB = -10dBm
