SETup:WDPChannel:SEMask

Last Updated: August 29, 2007

These commands allow you to set and query the Spectrum Emission Mask (SEM) settings associated with the Dedicated Physical Channel (DPCH) measurement suite.

• SETup:WDPChannel:SEMask:FREQuency:SPACing[?]

• SETup:WDPChannel:SEMask:LIMit[?]

• SETup:WDPChannel:SEMask:TTOLerance[?]

SETup:WDPChannel:SEMask:FREQuency:SPACing[?]

Sets/queries the frequency spacing between measurements for the 30 kHz and 1 MHz filters in the Spectrum Emission Mask measurement.

Setting Range: Depends upon the filter:

• 30 kHz filter: KHZ1 | KHZ5 | KHZ10

• 1 MHz filter: KHZ50 | KHZ100 | KHZ250   

Query Range: Depends upon the filter:

• 30 kHz filter: KHZ1 | KHZ5 | KHZ10

• 1 MHz filter: KHZ50 | KHZ100 | KHZ250   

*RST Setting: Depends upon the filter:

• 30 kHz filter: KHZ10

• 1 MHz filter: KHZ250   

Test Set Requirements: E6601A WCTS Program Version A.02 and above

Example:

' Set the frequency spacing between measurements for the 30 kHz and 1 MHz filters to 5 kHz and 100 kHz respectively.

TestSet.WriteString("SETup:WDPChannel:SEMask:FREQuency:SPACing KHZ5, KHZ100")

SETup:WDPChannel:SEMask:LIMit[?]

Sets/queries the pass/fail limits for the following frequency offsets in the Spectrum Emission Mask measurement:

• 30 kHz filter ±2.5 MHz

• 30 kHz filter ±3.5 MHz  

• 1 MHz filter ±3.5 MHz

• 1 MHz filter ±7.5 MHz

• 1 MHz filter ±8.5 MHz

• 1 MHz filter ±12.5 MHz

Setting Range: -80 to 10 dBc

Query Range: -80 to 10 dBc

Resolution: 0.01 dBc

*RST Setting:

• 30 kHz filter ±2.5 MHz: -35 dB

• 30 kHz filter ±3.5 MHz: -50 dB

• 1 MHz filter ±3.5 MHz: -35 dB

• 1 MHz filter ±7.5 MHz: -39 dB

• 1 MHz filter ±8.5 MHz: -49 dB

• 1 MHz filter ±12.5 MHz: -49 dB

Test Set Requirements: E6601A WCTS Program Version A.02 and above

Example:

' Set the pass/fail limits for the frequency offsets in the SEM measurement.

TestSet.WriteString("SETup:WDPChannel:SEMask:LIMit -37DB, -52DB, -37DB, -39DB, -51DB, -51DB")

SETup:WDPChannel:SEMask:TTOLerance[?]

Sets/queries the test tolerance level for the Spectrum Emission Mask measurement.

Setting Range: 0 to 100 dB

Query Range: 0 to 100 dB

Resolution: 0.01 dB

*RST Setting: 1.5 dB

Test Set Requirements: E6601A WCTS Program Version A.02 and above

Example:

' Set the test tolerance level for the Spectrum Emission Mask measurement to 2.5 dB.

TestSet.WriteString("SETup:WDPChannel:SEMask:TTOLerance 2.5DB")
