TP
Transmit Power (Config) (NV)
Use this command to set the output power level of the modulator transmit IF.
TP <dBm>
<dBm> parameter values are integers from 250 to 50, which represent -25.0 to
-5.0 dBm in 0.1 dBm steps. The default is 150.
From the front panel select:
Config > More > #:Modem > TxPwrLevel
TR
Transmit Symbol Rate (Config) (NV)
It is recommended that the PTD command be used instead of TR.
Use this nonvolatile configuration command to set the modulator symbol rate.
TR <mod sps>
<mod sps> parameter values are symbol rates of 4800 through 2500000 sps which
correspond to rates of 4.8 ksps through 2.5 Msps. The default is 1544000.
From the front panel select:
Config > More > #:Modem > TxSymRate
TS
Transmit Synthesizer Frequency (Config) (NV)
Use this nonvolatile configuration command to set the transmit IF carrier
frequency of the modulator. See the CM701 manual, Chapter 8 Command
Descriptions for further information.
TS <freq>
<freq> is the frequency in kHz at which the IF is centered.
■
52000 to 88000 (52 to 88 MHz)
■
104000 to 176000 (104 to 176 MHz)
The default setting is 70000. The frequency can be entered with a resolution of
Hertz: if only significant digits are entered, the remaining digits are assumed to be
zero.
