Making Measurements
RFM 150 Instruction Manual 2–21
Instead of making two measurements on one channel as in the
1 channel mode, the pilots mode provides a graph and numeric
readout of the visual carrier level for two different channels. The
vertical range is 20 dB; 10 divisions at 2 dB per division.
Pressing certain menu keys will reassign the function keys while
leaving the pilots measurement display on screen (for example,
pressing STORE to store a measurement result). Press ESC to exit
the other menu and return the full pilots display.
To change to another level measurement mode, press LEVEL. To
change to another menu, press the desired menu key.
Editing the Pilot Frequencies
The channels being measured are the high and low pilots. To change
the high and low pilot frequencies, press UTIL, select CONFIG, then
MEAS SETUP. The function keys will be assigned to the four fields
available for edit. An arrow cursor along the left edge of the screen
will indicate the selected parameter. Select high or low pilot by
pressing the corresponding function key, then use the knob or keypad
to edit the frequency. A keypad entry must be terminated with
CHAN, MHz, or ENTER. A partial keypad entry can be cancelled by
pressing ESC or backspacing one space past an empty field. The
previous frequency will be restored, without change.
Exit.
To change to another menu, press the new menu key. Pressing
certain menu keys will reassign the function keys while leaving the
meter mode display on screen (for example, pressing STORE to store
a measurement result). Press ESC to exit the other menu and restore
the pilots mode function keys. To change to another level measure-
ment mode, press the corresponding function key.
