11.2 Commands
After connecting to Channel 1, Channel 2, or Channel 3 (the combiner), the command prompt displays. The
following commands configure the Tape Out on Q/Video B. Anything past the ‘#’ is a
comment, and can be
discarded.
aho b p0t; # Routes Physical channel 0 tape output source to Q/Video B
ahm x.x; # Sets the tape out mixer to x.x MHz
ahm b 1; # Enables the tape out mixer on Q/Video B output
The following commands configure the Tape Out on I/Video A.
aho a p0t; # Routes Physical channel 0 tape output source to I/Video A
ahm x.x; # Sets the tape out mixer to x.x MHz
ahm a 1; # Enables the tape out mixer on I/Video A output
In both cases, the x.x MHz is in the range of 0.075 to 20.0 MHz. Frequencies outside of that range result in
unpredictable behavior.
Example:
To configure Q/Video B out for 5.1 MHz center frequency:
Aho b p0t
ahm 5.1
ahm b 1
To configure I/Video A out for 2.8 MHz center frequency:
aho a p0t
ahm 2.8
ahm a 1
11.2.1 Notes
This is not a persistent configuration. Changing modes or power cycling the unit cause the Video outputs to revert to
their normal, baseband outputs.
While the Tape Out can be configured simultaneously on I/Video A and Q/Video B, they cannot have independent
frequencies. The frequency specified by ‘ahm x.x’ will be used for BOTH.
11.3 3U Connectors
The Tape Output feature on the 3U Receiver uses the I/Video A, Q/Video B, Video C, and Video D outputs. The 3U
connectors are listed in Table 15 and locations are illustrated in Figure 310.
