Sets the power level offset for the TETRA signal generator. Please note that changing this value will also cause the display of the Tx output level to adjust to the new offset. For example, if the output level is set to 0 dBm and the level offset is then set to 10 dB external gain, the max limit and value of the output level will be adjusted to 10 dBm. The query returns a value from -100 to 100. A negative sign means external gain and no sign means external loss.
Cmd Parameters:
<value>
Query Parameters:
NA
Range
100 dB Ext Loss to 100 dB Ext Gain
Default Value
0 dB
Default Unit
dB
Example
To set the signal generator offset to 10 dB external gain:
:SOURce:CORRection:OFFSet -10
Front Panel Access
Amplitude, Tx Power Offset
:SOURce:DM:PATTern <value> :SOURce:DM:PATTern?
Description
Sets the signal generator pattern. The command only accepts the numerical value of the position the pattern is on the list (starting from 0). To retrieve the numerical values attached to each pattern, use :SOURce:DM:PATTern:LIST? The query returns a numerical value corresponding to the position of the current Tx pattern in the pattern list.
Cmd Parameters:
<value>
Query Parameters:
NA
Range
0 to Number of Patterns
Default Value
0
Default Unit
NA
Example
To set the pattern to the 3rd pattern in the signal generator pattern list:
:SOURce:DM:PATTern 2
Front Panel Access
Setup, Tx Pattern
:SOURce:DM:PATTern:LIST?
Description
Retrieves a list of signal generator pattern names and the index number that is used to set the pattern. The pattern names match the names of the pattern list that pops up when the Tx Pattern button is pushed and the index number is the position of the pattern on that list. The command returns a list with the following format and patterns:
Sets the signal generator center frequency. Please note that setting the center frequency will restart the sweep. The query returns the current signal generator frequency in Hz.
Cmd Parameters:
<value>
Query Parameters:
NA
Range
500000 Hz to 1600000000 Hz
Default Value
800000000 Hz
Default Unit
Hz
Example
To set the signal generator center frequency to 145 MHz:
Sets the output power level for the TETRA signal generator. Please note that changing the Tx power offset will also cause the display of this to adjust to the new offset. For example, if the output level is set to 0 dBm and the Tx level offset is then set to 10 dB external gain, the max limit and value of the Tx output level will be adjusted to 10 dBm. The query returns the current Tx output level.
The query will be returned in the unit that is selected through the Tx Units button on the front panel or with the command: UNIT:POWer:TX. The set command must be sent using the units selected. If the receiver unit has been set to dBm, the generator output level is returned in dBm and must be set in dBm. If the unit is set to Watts, the generator output level is returned in fW (10-15 W) and must be set in fW. If the unit is set to Volts, the generator output level is returned in fV (10-15 V) and must be set in fV.
Cmd Parameters:
<value>
Query Parameters:
NA
Range
0 dBm to -130 dBm or 1 mW to 1 fW or 70710678 fV to 223606797749978 fV
Default Value
0 dBm or 1 mW or 223606797749978 fV
Default Unit
dBm or fW or fV
Example
To set the signal generator output level to -10 dBm:
:SOURce:POWer -10
Front Panel Access
Amplitude, Tx Output Lvl
:SOURce:STATe OFF|ON|0|1 :SOURce:STATe?
Description
Turns the signal generator ON or OFF. Please note that the Generator ON/OFF button will toggle depending on the state. When the signal generator is on, the button will show Turn Sig-Gen OFF. When the signal generator is off, the button will show Turn Sig-Gen ON. The query returns the current signal generator state. A return value of 1 means ON and a return value of 0 means OFF.
