vertically on the screen. If the signal at the marker frequency
is greater than the reference level, the word OVER will be
displayed in place of the level readout. If this happens,
increase the reference level until the entire signal appears
vertically on screen.
5. Select center frequency (the frequency at the horizontal center of
the display) as follows:
a. Press CHAN to assure that the knob is not assigned to REF,
MKR, or SPAN. (This also assigns the knob to tune by
channel. For frequency tuning, press MHz instead of CHAN.)
b. Turn the knob and note that the channel readout in the upper
left corner of the screen changes. This will move the trace
horizontally on the screen.
6. Use the marker to read the signal level as follows:
a. Press F2 until MKR is selected (the MKR label is outlined).
b. Turn the knob to move the marker (the solid vertical line).
Note that this changes the marker frequency readout near the
lower left corner of the measurement display. The signal level
at the marker frequency is displayed directly below the
marker frequency readout.
P. Executing the 24 Hour Test Sequence
A series of measurements can be made by executing one of the
automated test sequences that are loaded in the RFM 150. The results
of the tests will be stored, and can be accessed through the store
menu.
The following procedure shows you how to enter the site name and
temperature that will be stored with the test results, how to execute
the factory-installed 24 hour test sequence, how to abort the
sequence, and how to access the results of the sequence.
For information on creating and importing new sequences, refer to
the user manual for the companion CSS150 software.
1. Press STORE, then press F3 to select SITE NAME. Check the
ACTIVE SITE NAME near the upper left corner of the screen. If
this is correct, proceed to step 2.
