These commands allow you to set and query general settings associated with the Dedicated Physical Channel (DPCH) measurement suite.
For more information on the conventions used in the programming examples click here.
Sets/queries the burst synchronization mode for the DPCH measurement suite.
This setting does not apply to the EVM, FERR and PCDE measurements since these measurements are fixed to use the MIDamble sync according to the standard requirement.
Setting Range: NONE | MIDamble
Query Range: NONE | MID
*RST Setting: MID
Test Set Requirements: E6601A WCTS Program Version A.05 and above
Example:
' Set burst synchronization to midamble.
TestSet.WriteString("SETup:TDPChannel:BURSt:SYNC MID")
Sets/queries the trigger state for the Dedicated Physical Channel measurement suite. See Triggering of Measurements.
Setting Range: Single trigger mode = 0 | OFF, Continuous trigger mode = 1 | ON
Query Range: 0 | 1
*RST Setting: 0 | OFF
Test Set Requirements: E6601A WCTS Program Version A.05 and above
Example:
' Set the measurement suite to single trigger mode.
TestSet.WriteString("SETup:TDPChannel:CONTinuous OFF")
The setting form of this command performs two functions: (1) sets the multi-measurement count for the Dedicated Physical Channel measurement suite (see SETup:TDPChannel:COUNt:NUMBer[?]) and (2) sets the multi-measurement count state to on (see SETup:TDPChannel:COUNt:STATe[?]).
The query form of this command returns the current Dedicated Physical Channel measurement suite multi-measurement count value.
Setting Range: 1 to 999
Query Range: 1 to 999
*RST Setting: 10
Test Set Requirements: E6601A WCTS Program Version A.05 and above
Example:
' Set the state to on and the multi-measurement count value to 100.
TestSet.WriteString("SETup:TDPChannel:COUNt 100")
Sets/queries the multi-measurement count for the Dedicated Physical Channel measurement suite.
Setting Range: 1 to 999
Query Range: 1 to 999
Resolution: 1
*RST Setting: 10
Test Set Requirements: E6601A WCTS Program Version A.05 and above
Example:
' Set the multi-measurement count value to 5.
TestSet.WriteString("SETup:TDPChannel:COUNt:NUMBer 5")
Sets/queries the Dedicated Physical Channel measurement suite, multi-measurement state.
Setting Range: 0 | OFF | 1 | ON
Query Range: 0 | 1
*RST Setting: 0 | OFF
Test Set Requirements: E6601A WCTS Program Version A.05 and above
Example:
' Turn on DPCH measurement suite multi-measurements.
TestSet.WriteString("SETup:TDPChannel:COUNt:STATe ON")
Sets/queries the measurements to enable for the Dedicated Physical Channel measurement suite.
After you perform a full preset of the test set, switch applications, or restart the test set, you must either send this command or the INITiate:TDPChannel[:ON] command, with one or more parameters specifying the measurements you want the RF Channel measurement suite to perform. Otherwise, if you attempt to use the INITiate:TDPChannel[:ON] command without specifying any parameters, the following error message is reported:
“Operation rejection; Sub-measurements must be enabled using ‘SETup:TDPChannel:INITiate <args>’ or ‘INITiate:TDPChannel[:ON] <args>’ before ‘INITiate:TDPChannel[:ON] can be accepted.”
Specifying a value of NONE disables all measurements in the suite.
If this command or the INITiate:TDPChannel[:ON] command has not enabled measurements in the suite since a power up, preset, or an application switch, the query form of this command returns a value of UNKN (short for UNKNown). This value indicates that you have not explicitly set up the measurements to enable for the Dedicated Physical Channel measurement suite, so it is indeterminate which sub-measurements are enabled.
Setting Range: One or more of the following values, separated by commas:
ACLRatio
EVM
FERRor
MPOWer
PCER
RRCPower
SEMask
NONE
Query Range: One or more of the following values, separated by commas:
ACLR
EVM
FERR
MPOW
PCER
RRCP
SEM
NONE
UNKN
*RST Setting: NONE
Test Set Requirements: E6601A WCTS Program Version A.05 and above
Example:
' Set the Dedicated Physical Channel measurement
suite to include Mean Power
' and Adjacent Channel Leakage Ratio sub-measurements.
TestSet.WriteString("SETup:TDPChannel:INITiate MPOW,ACLR")
Queries the number of measurements enabled for the Dedicated Physical Channel measurement suite.
Query Range: 1 to 7
*RST Setting: 3
Test Set Requirements: E6601A WCTS Program Version A.05 and above
Example:
' Query the number of sub-measurements enabled for the Dedicated Physical Channel measurement suite.
TestSet.WriteString("SETup:TDPChannel:INITiate:COUNt?'")
The setting form of this command performs two functions: (1) sets the measurement timeout value in seconds for the Dedicated Physical Channel measurement suite (see SETup:TDPChannel:TIMeout:TIME[?]) and (2) sets the measurement timeout state to on (see SETup:TDPChannel:TIMeout:STATe[?]).
The query form of this command returns the current Dedicated Physical Channel measurement suite timeout value.
The units (S|MS) are optional, if no units are specified then units default to S.
Setting Range: 0.1 to 999.9 s
Query Range: 0.1 to 999.9 s
Resolution: 0.01 s
*RST Setting: 10 s
Test Set Requirements: E6601A WCTS Program Version A.05 and above
Example:
' Set the measurement suite timeout to 20 seconds and set the timeout state to on.
TestSet.WriteString("SETup:TDPChannel:TIMeout 20S")
Sets/queries the DPCH measurement suite's timeout (see Measurement Timeouts) state.
Setting Range: 0 | OFF | 1 | ON
Query Range: 0 | 1
*RST Setting: 0 | OFF
Test Set Requirements: E6601A WCTS Program Version A.05 and above
Example:
' Set the timeout state to On.
TestSet.WriteString("SETup:TDPChannel:TIMeout:STATe ON")
Sets/queries the DPCH measurement suite's timeout (see Measurement Timeouts) setting to be used when the timeout state is set to ON.
Setting Range: 0.1 to 999.9 s
Query Range: 0.1 to 999.9 s
Resolution: 0.01 s
*RST Setting: 10 s
Test Set Requirements: E6601A WCTS Program Version A.05 and above
Example:
' Set the timeout to 5 seconds.
TestSet.WriteString("SETup:TDPChannel:TIMeout:TIME 5S")
Sets/queries the DPCH measurement suite's trigger delay setting. See Triggering of Measurements.
This setting can be used to delay the measurement suite's trigger in order to start a measurement suite during a specific timeslot in the frame. For example, a 1.333 ms delay would cause the trigger to wait until after the first two timeslots have elapsed.
Setting Range: -10 to 10 milliseconds
Query Range: -10 to 10 milliseconds
Resolution: 0.0001 millisecond
*RST Setting: 0 milliseconds
Test Set Requirements: E6601A WCTS Program Version A.05 and above
Example:
' Set the trigger delay to 1 ms.
TestSet.WriteString("SETup:TDPChannel:TRIGger:DELay 1MS")
Sets/queries the DPCH measurement suite's trigger source. See Triggering of Measurements.
Setting Range: RISE | IMMediate | EXTernal
Query Range: RISE | IMM | EXT
*RST Setting: RISE
Test Set Requirements: E6601A WCTS Program Version A.05 and above
Example:
' Set the trigger source to Immediate.
TestSet.WriteString("SETup:TDPChannel:TRIGger:SOURce IMM")
