SCPI Commands without GUI Functions
The software provides a standard list of commands created for this software. The list also provides links to the command descriptions.
Some command exceptions are included in this topic. The instrument commands that have UI Parameters are included here for ease of use.
For information on real-time E4438C compatible commands, for your instrument, refer to E4438C Compatible Commands with the N5172B/N5182B.
Use this topic to find SCPI commands that do not have corresponding UI parameters supported by either of the N5172B EXG and the N5182B MXG vector signal generators.

[:SOURce]:RADio:WCDMa:TGPP[:BBG]:TRIGger:DELay <val>
[:SOURce]:RADio:WCDMa:TGPP[:BBG]:TRIGger:DELay?
n/a
This command defines the time delay for a trigger being sent to the baseband generator.
Adjusts the scaling of the I and Q data. Reducing the runtime scaling prevents the over ranges from happening. Runtime scaling is also used to scale signals relative to each other in any "Generate and Sum" or MIMO configurations where channel summing occurs. When a waveform file is selected, this value is read from the file; however, it may be changed, even while the waveform is playing.
0.000 to 21s (0 ms to 21s)
(The resolution of value is 5 ns. The value is clipped to this resolution.)
[:SOURce]:RADio:WCDMa:TGPP[:BBG]:POLarity[:ALL] NORMal|INVert
[:SOURce]:RADio:WCDMa:TGPP[:BBG]:POLarity[:ALL]?
n/a
This command selects the polarity for the Q channel.

NORMal
|
This choice selects normal phase polarity.

[:SOURce]:RADio:WCDMa:TGPP[:BBG]:POWer:ORMS?
n/a
This query returns the value of the Baseband RMS power (unscaled).
[:SOURce]:RADio:WCDMa:TGPP[:BBG]:ULINk:DPCCh:TPOWer?
n/a
This query returns the “Total Power” value displayed on the user interface (UI). The power value is the relative power difference between the total in-channel signal power and the active channel reference power (0dB).
If the parameter set by the following command is changed while the signal is active, the :ULINk:APPLy command or Apply Needed (
) button must be executed for the change to occur.
[:SOURce]:RADio:WCDMa:TGPP[:BBG]:ULINk:DPDCh:TPOWer?
n/a
This query returns the “Total Power” value displayed on the user interface (UI). The power value is the relative power difference between the total in-channel signal power and the active channel reference power (0dB).
[:SOURce]:RADio:WCDMa:TGPP[:BBG]:ULINk:PADJust EQUal|SCALe
n/a
|
EQUal
|
This choice will adjust all channel powers to equal power settings.
|
|
SCALe
|
This choice will scale the channel power levels so that the sum of the powers are equal to 0 dB.
|
[:SOURce]:RADio:WCDMa:TGPP[:BBG]:ULINk:PRACh:AICH:NUMBer?
n/a
This query returns the number of received acquisition indication channel (AICH) trigger during one configured physical random access channel (PRACH) signal generation.
The result value can be queried after the PRACH signal generation is completed and until the next PRACH generation trigger is received.
The signal begins when the PRACH start trigger and ends when the specified number of signals are generated.
To specify a number of PRACHes, refer to :ULINk:PRACh[:SINGle]:PREamble:NUMBer.
A -1 status represents a PRACH generation is ongoing.
[:SOURce]:RADio:WCDMa:TGPP[:BBG]:ULINk:PRACh[:SINGle]:PREamble:POWer:AVERage?
n/a
This query returns the average power of preambles that were sent before the acquisition indication channel (AICH) trigger was received.
The average power value can be queried after the physical random access channel’s (PRACH) signal generation is completed.
[:SOURce]:RADio:WCDMa:TGPP[:BBG]:ULINk:PRACh:TPOWer?
n/a
This query returns the total power value of the physical random access channels (PRACH).
The value is the relative power difference between the total in-channel signal power of the PRACH message part and the active channel reference power (0dB) in the message part.
This command is used for single and multiple physical random access channel (PRACH) modes.
[:SOURce]:RADio:WCDMa:TGPP[:BBG]:ULINk:TGAP:PSI[1]|2|3|4|5|6:POWer?
n/a
This query returns each power level for a compressed slot.
The return string has five real numbers followed by dBm (for normal power) or dB (for before/after gap power) separated by a single space character. When a value does not exist because of a specified compressed pattern (Example: Gap2 does not exist when TGD is “UNDefined”), it returns “–dB.”
Normal power value represents an actual power level in dBm and relative power is represented in dB.
[:SOURce]:RADio:WCDMa:TGPP[:BBG]:ULINk:TGAP:SCFN <val>
[:SOURce]:RADio:WCDMa:TGPP[:BBG]:ULINk:TGAP:SCFN?
n/a
This command sets the stop connection frame number (CFN) when the stop trigger is used.
When the stop trigger is received at the signal generator, the next stop CFN, the compressed mode will finish even if the transmission gap pattern repetition count (TGPRC) is still remaining.
The compressed mode stop trigger must be used for this command to executed.
If the parameter set by the following command is changed while the signal is active, the :ULINk:APPLy command or Apply Needed () button must be executed for the change to occur.
0 to 255
[:SOURce]:RADio:WCDMa:TGPP[:BBG]:ULINk:TSTatus:COMPressed?
n/a
This query returns the status of compressed pattern generation. A “0” response indicates the compressed mode pattern signal is not generating. A “1” response indicates that the compressed mode pattern signal is generating.
[:SOURce]:RADio:WCDMa:TGPP[:BBG]:ULINk:TSTatus:RACH?
n/a
This query returns the status of the physical random access channel (PRACH). A “0” response indicates the PRACH signal is not generating. A “1” response indicates that the PRACH signal is generating.
[:SOURce]:RADio:WCDMa:TGPP[:BBG]:ULINk[:TGRoup[1]]:DCH[1]|2|3|4|5|6:DATA:BER:ACTual?
n/a
This query returns the actual inserted error ratio in the uplink dedicated channel (DCH) selected.
The actual bit error rate can be different from the specified bit error rate due to the
internal bit generation.
[:SOURce]:RADio:WCDMa:TGPP[:BBG]:ULINk[:TGRoup[1]]:DCH[1]|2|3|4|5|6:DATA:BLER:ACTual?
n/a
This query returns the actual block error ratio inserted.
The actual block error rate can be different from the specified block error rate due to the internal bit generation.
[:SOURce]:RADio:WCDMa:TGPP[:BBG]:ULINk[:TGRoup[1]]:DCH[1]|2|3|4|5|6[:STATe] ON|OFF|1|0
[:SOURce]:RADio:WCDMa:TGPP[:BBG]:ULINk[:TGRoup[1]]:DCH[1]|2|3|4|5|6[:STATe]?
n/a
This command enables or disables the operating state of the dedicated channel (DCH) selected.
[:SOURce]:RADio:WCDMa:TGPP[:BBG]:ULINk[:TGRoup[1]]:RACH[1]:DATA:BER:ACTual?
n/a
This query returns the actual error ratio inserted.
The specified error ratio and actual ratio will not match when the internal bit generation goes into “pre-computing” mode.
0 to 5000
[:SOURce]:RADio:WCDMa:TGPP[:BBG]:ULINk[:TGRoup[1]]:RACH[1]:DATA:BLER:ACTual?
n/a
This query returns the actual error ratio inserted.
The specified error ratio and actual error ratio will not match when the internal bit generation goes into “pre-computing” mode.
