Communication Mode Field Definition - Aeroflex NAV 2000R Operation Manual

Aeroflex Operation Manual
IDENT MODE
This toggle menu selects the Marker Beacon modulation technique: OFF, TONE, CODE. When the
default option of CODE is selected, the NAV 2000R will pulse the modulation on and off at a rate as
defined by the Beacon selected. If TONE is selected, the NAV 2000R will modulate a constant marker
beacon tone. If OFF is selected, the tone will not be modulated.

3.5.12 COMMUNICATION MODE FIELD DEFINITION

The Communication mode is entered by pressing and releasing the COM mode button. This mode
allows testing of communication equipment by modulating one or two tones simultaneously. The user
may specify the frequency and modulation percentage of both tones. The sum of the tones is limited to
99% modulation.
RF LEVEL
This field allows the RF level to be programmed. The RF level may be programmed with 1/10th dBm
resolution using either dBm or uV/mV units. DBm numbers are entered using the ENT key. Microvolts
and millivolt numbers may be entered using the uV and mV keys (STO/RCL) respectively. The default
displayed units (normally dBm) may be changed by pressing the SEL key and then pressing either the
uV, mV, or dBm keys.
FREQ. MHz
This field allows the RF frequency to be programmed.
CHANNEL
This field steps the RF frequency output up and down by using the cursor control up and down arrow
keys.
TONE #1 FREQUENCY
This field is used to program the first tone frequency from 10.0 Hz to 18000.0 Hz in 0.1 Hz steps. The
default for this field is 1000 Hz.
TONE #1 MODULATION
This field programs the modulation percentage of the first tone. This is a numeric entry field type and is
programmable from 0 to 99% in 0.01% steps. The default value for this field is 30%. The sum of the
modulated tones will be limited to be no more than 99%.
TONE #2 FREQUENCY
This field is used to program the second tone frequency from 10.0 Hz to 18000.0 Hz in 0.1 Hz steps. The
default for this field is 2000 Hz.
TONE #2 MODULATION
This field programs the modulation percentage for the second tone. This is a numeric entry field type and
is programmable from 0 to 99% in 0.01% steps. The default setting is 0% modulation. The sum of the
modulated tones will be limited to no more than 99%.
