smos [TPTlength [SendTLP [ReceiveTLP]]]
Use this command to set the TPT (test progress tone) duration, Send TLP (test level point)
and Receive TLP.
•
TPTlength is the length of the TPT burst [1..99] seconds.
•
SendTLP and ReceiveTLP are the send and receive transmission level points [–50..0]
dBm.
If you send the command
smos
without any parameters, the 925VST will report the
current SMOS test line parameters.
Example: Current SMOS test line parameter is
TPT burst length: 10s
Send TLP:
–1dBm
REceive TLP:
–10dBm

ARAMETERS
pvit [filtertype [level]]
Use this command to set the filter type and transmit signal level.
•
filter type is either 'c' (C-message) or 'p' (Psophemetric); C-message for North
America, Psophometric for all other places.
•
level is test signal level in dBm and must be an integer from –30 to 0.
If you send the command
pvit
without any parameters, the 925VST will report the current
PVIT test line parameters.
Example: Current PVIT Sender test line parameter is
filter:
C-message
Test signal level is –16dBm

ARAMETERS
egen [level_1 delay_1 [level_2 delay_2]]
Use this command to set the inserted loss and inserted delay of up to two echoes
generated by this test line.
•
level(dB) must be an integer between –60 to 9 for 4-wire or –40 to 9 for 2-wire.
•
delay must be an integer between 16 to 600 (ms).
If you send the command
egen
without any parameters, the 925VST will report the
current EGEN test line parameters.
Example: Current echo generator parameter is
level_1: –10dBm, delay_1: 30ms

tlstart
The test line start command takes no arguments. This command forces the test line to start.
This command only applies in 4-wire mode.
