IQ Voltage Scale
[:SOURce]:RADio:WCDMa:TGPP[:BBG]:IQ:SCALe <
40.00 to 0.00dB>
[:SOURce]:RADio:WCDMa:TGPP[:BBG]:IQ:SCALe?
This command adjusts the total IQ output power in the 2 box setup. Changing this value
affects the total power and channel power levels will be internally scaled. The output
power is automatically calculated when the Voltage Other ESG field changes.
Range: 0 to
40 dB
*RST: 0.00
IQ Total Voltage Query
[:SOURce]:RADio:WCDMa:TGPP[:BBG]:IQ:TVOLtage?
This command query returns the total voltage level value from the ESG. This value will
displayed in the Voltage This ESG data field.
*RST: 0.00
IQ Total Voltage Paired
[:SOURce]:RADio:WCDMa:TGPP[:BBG]:IQ:TVPaired <0 to 4V>
[:SOURce]:RADio:WCDMa:TGPP[:BBG]:IQ:TVPaired?
This command adjusts the total IQ output power of the paired ESG. The IQ Voltage Other
ESG value is for a 2-ESG setup. Entering a value in the IQ Voltage Other ESG field
forces a calculation of the IQ voltage scale.
*RST: 0
Link Down Up
[:SOURce]:RADio:WCDMa:TGPP[:BBG]:LINK DOWN|UP
[:SOURce]:RADio:WCDMa:TGPP[:BBG]:LINK?
This command sets the ESG for uplink or downlink parameters.
*RST: Down
Phase Polarity
[:SOURce]:RADio:WCDMa:TGPP[:BBG]:POLarity[:ALL] NORMal|INVerted
[:SOURce]:RADio:WCDMa:TGPP[:BBG]:POLarity[:ALL]?
This command selects the polarity for the Q channel.
*RST: Normal
