TESTS (Channel Information)
Delete Ch
This field allows you to delete a channel from the frequency table at the bottom of
the screen.
Insert Ch
This field allows you to enter a new channel in frequency table at the bottom of
the screen.
Operating Considerations
You are required to specify if the test channel is a prime test channel. Prime test
channels are the radio channels primarily used by the radio operator; they are the
channels you are the most concerned about testing.
Use the
RX Chan Info
or
TX Chan Info
fields if the channel requires a tone
code or frequency for testing radios that have CTCSS (Continuous Tone-
Controlled Squelch System) squelch.
For example, if your radio uses a CTCSS tone of 91.5 Hz, you could enter the tone
frequency in both RX and TX channel information fields as
CT FR91.5
or you
could enter the tone code itself as
CT ZZ
. The specific entries are described in
your HP 11807A software manual.
When testing cellular radios, the Channel Information is the channel number you
are testing (don’t confuse this with the
Chan#
field used to list channels on this
screen). When the cellular radio channel number is entered, the HP 11807A
software automatically sets the channel frequencies when testing. You do not
need to enter the RX and TX frequencies because they correspond directly to the
channel numbers.
NOTE: Enter
−
1 in the
RX
and
TX
test frequency fields to have all subsequent channels ignored when
testing is started.
