Readouts on the MODULATION Meter (1) will display according to the
Mod-
ulation METER Control (4) setting and on the FREQ ERROR Meter (36) ac-
cording to the FREO ERROR Meter Range Selector Control (35). including:
1.
With the Modulation METER Control (4) set to 2 KHz/%x10 or
6 KHz/%x10, the MODULATION Meter (1) displays the SAT Deviation.
2.
With the Modulation METER Control (4) set to 20 KHz/%x10 or 60
KHz/%x10, the MODULATION Meter (1) displays Signal Tone Deviation.
3.
With the FREQ ERROR Meter Range Selector Control (351 at any RF
setting, the FREQ ERROR Meter (36) shows the UUT transmitter
frequency error.
4.
With the FREQ ERROR Meter Range Selector Control (35) set to any
AUDIO setting, the FREQ ERROR Meter (36) will show the UUT SAT
and FM/AM-1200S SAT frequency difference.
5.
It may be necessary to mute the UUT microphone for
a stable Audio Frequency Error reading.
Frequency Error and Deviation levels may be digitati]l· checked and
displayed on the VFD during the test
