Customizing Testing
Specifying Channel Information (Edit Frequency)
For each channel that you wish to specify, you must enter the following
information into the
Edit Frequency screen:
• RX Freq (MHz)
• Enter the receive frequency of your radio in (MHz).
• TX Freq (MHz)
• Enter the transmit frequency of your radio in (MHz).
NOTE: Enter a −1 in the RX or TX test frequency fields to have all subsequent frequencies ignored
when testing is started.
• RX Chan Info
• If you are testing receiver CTCSS or CDCSS (test parameter 8 is set=1), you must
enter the receive squelch frequency or code. Otherwise, leave this field empty.
•TX Chan Info
• If you are testing transmitter CTCSS or CDCSS (test parameter 23 is set=1), you
must enter the transmit squelch frequency or code. Otherwise, leave this field
empty.
• Test? (yes/no) specifies whether you want to test the UUT at this channel. If set to
“No” then the UUT will not be tested at that channel, but you may retain the channel
information in the table for later use. If set to “Yes” then the channel will be used as
defined by settings of Prime? and All Chans? fields.
• Prime? (yes/no) specifies which channels are “prime”. Select “Yes” if you want to
test the UUT at this channel on all the tests in the procedure. Select No if you want to
test the UUT at this channel on just a subset of tests, which are designated by selecting
Yes in the All Chans field of the Edit Seqn screen. See All Chans? in
"Changing the Order of Tests (Edit Sequence)" on page 68 for more information.
For information on saving the frequency table, see "Saving a Test Procedure Using
the Procedure Manager" on page 83
.
The
All Chans field in the Edit Seqn screen interacts closely with the Prime?
field on the
Edit Freq screen. When the software runs, it begins by retrieving
the first channel entered into the
Edit Freq screen. It then checks the response
in the
Test? field to determine if the UUT should be tested at that channel at this
time. If there is a
No response in the Test? field, the software will go to the next
channel in the table. If there is a
Yes response in the Test? field, the software
will check if the channel is
Prime.
A
Yes response in the Prime? field indicates to test the UUT at that channel on
the entire sequence of tests in the procedure. A
No response in the Prime? field
indicates to test the UUT at that channel on a subset of tests in the procedure. The
subset of tests is determined by a
Yes response in the All Chans? field.
Therefore, tests with a
No response in the All Chans? field will be run on prime
channels only.
