These commands allow you to set and query general settings associated with the Reverse Traffic Channel (RTCH) measurement suite.
For more information on the conventions used in the programming examples click here.
Sets/queries the trigger arm state for the Reverse Traffic Channel (RTCH) 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.04 and above
Example:
' Set the measurement suite to single trigger mode.
TestSet.WriteString("SETup:CRTChannel:CONTinuous OFF")
The setting form of this command performs two functions: (1) sets the multi-measurement count for the Reverse Traffic Channel measurement suite (see SETup:CRTChannel:COUNt:NUMBer[?]) and (2) sets the multi-measurement count state to On (see SETup:CRTChannel:COUNt:STATe[?]).
The query form of this command returns the current Reverse Traffic 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.04 and above
Example:
' Set the state to on and the multi-measurement count value to 100.
TestSet.WriteString("SETup:CRTChannel:COUNt 100")
Sets/queries the multi-measurement count for the Reverse Traffic Channel measurement suite. This command is only applied when the multi-measurement count state is ON (see SETup:CRTChannel:COUNt:STATe[?]).
Setting Range: 1 to 999
Query Range: 1 to 999
*RST Setting: 10
Test Set Requirements: E6601A WCTS Program Version A.04 and above
Example:
' Set the multi-measurement count value to 5.
TestSet.WriteString("SETup:CRTChannel:COUNt:NUMBer 5")
Sets/queries the multi-measurement state of the Reverse Traffic Channel measurement suite.
Setting Range: 0 | OFF | 1 | ON
Query Range: 0 | 1
*RST Setting: 0 | OFF
Test Set Requirements: E6601A WCTS Program Version A.04 and above
Example:
' Turn on RTCH measurement suite multi-measurements.
TestSet.WriteString("SETup:CRTChannel:COUNt:STATe ON")
Sets/queries the measurements to enable for the Reverse Traffic 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:CRTChannel[:ON] command, with one or more parameters specifying the measurements you want the Reverse Traffic Channel measurement suite to perform. Otherwise, if you attempt to use the INITiate:CRTChannel[:ON] command without specifying any parameters, the following error message is reported:
“Operation rejection; Sub-measurements must be enabled using ‘SETup:CRTChannel:INITiate <args>’ or ‘INITiate:CRTChannel[:ON] <args>’ before ‘INITiate:CRTChannel[:ON] can be accepted.”
Specifying a value of NONE disables all measurements in the suite.
If this command or the INITiate:CRTChannel[: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 Reverse Traffic Channel measurement suite, so it is indeterminate which sub-measurements are enabled.
Setting Range: One or more of the following values, separated by commas:
CPOWer
OBWidth
TXSPurious
Query Range: One or more of the following values, separated by commas:
CPOW
OBW
TXSP
*RST Setting: UNKN
Test Set Requirements: E6601A WCTS Program Version A.04 and above
Example:
' Set the Reverse Traffic Channel measurement
suite to include Channel Power
' and Occupied Bandwidth sub-measurements.
TestSet.WriteString("SETup:CRTChannel:INITiate CPOWer,OBWidth")
Queries the number of measurements enabled for the Reverse Traffic Channel measurement suite.
Setting Range: 1 to 3
Query Range: 1 to 3
*RST Setting: 3
Test Set Requirements: E6601A WCTS Program Version A.04 and above
Example:
' Query the number of sub-measurements enabled for the Reverse Traffic Channel measurement suite.
TestSet.WriteString("SETup:CRTChannel:INITiate:COUNt?'")
The setting form of this command performs two functions: (1) sets the measurement timeout value in seconds for the Reverse Traffic Channel measurement suite (see SETup:CRTChannel:TIMeout:TIME[?]) and (2) sets the measurement timeout state to on (see SETup:CRTChannel:TIMeout:STATe[?]).
The query form of this command returns the current Reverse Traffic 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.04 and above
Example:
' Set the measurement suite timeout to 20 seconds and set the timeout state to on.
TestSet.WriteString("SETup:CRTChannel:TIMeout 20S")
Sets/queries the Reverse Traffic Channel 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.04 and above
Example:
' Set the timeout state to On.
TestSet.WriteString("SETup:CRTChannel:TIMeout:STATe ON")
Sets/queries the Reverse Traffic Channel 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.04 and above
Example:
' Set the timeout to 5 seconds.
TestSet.WriteString("SETup:CRTChannel:TIMeout:TIME 5S")
Sets/queries the Reverse Traffic Channel measurement suite's trigger source. See Triggering of Measurements.
Setting Range: ARB | IMMediate | EXTernal
Query Range: ARB | IMM | EXT
*RST Setting: IMM
Test Set Requirements: E6601A WCTS Program Version A.04 and above
Example:
' Set the trigger source to Immediate.
TestSet.WriteString("SETup:CRTChannel:TRIGger:SOURce IMM")
