Next, use the  keys to set Rx (up converter operation) as On or Off. The
default mode is Off. Press ENTER.
6.2.3.1.1 (CONFIG:) OUTPUT Submenu (OPTIONAL DUAL IF RACK
MOUNT CONVERTERS)
Comtech EF Data provides the ability to switch the input IF frequency between
70 MHz and 140 MHz. For converters equipped with this optional hardware
configuration, the (CONFIG:) OUTPUT submenu appears as follows:
Frq=03627.125 MHz IF=140
Atten=02.00 dB Rx = Off
On the top line, press the ENTER key to set the converter RF Frq (Frequency).
You may edit the current frequency channel from RF
Low
to RF
High
MHz (e.g.;
05845.000 to 06725.000 MHz for Model UT-4505/I) in 125 kHz steps (1 kHz steps
optional). Use the   keys to select a digit, and then use the  keys to
change that digit.
Next, set the converter IF Frequency. Use the   keys to jump to this setting,
and then use the  keys to select 70 MHz or 140 MHz. The default is 70 MHz.
On the bottom linescreen that follows, set the converter Atten (Attenuation).
You may select an attenuation setting from 0.00 to 25.00 dB in 0.25 dB steps (0.1
dB steps optional). The default setting is 10.00 dB. Use the   keys to select a
digit, and then use the  keys to change that digit. Press ENTER.
1) The actual IF bandwidth is maintained as the standard ±18 MHz
(±20 MHz) of the 70 MHz configurations.
2) The mute behavior after changing the IF frequency is the same as
the normal mute behavior after changing the RF frequency.
3) You may not “mix” dual IF converters with standard converters
when operating in a redundant system.
