FETCh:DOWQuality

Function

Queries the waveform quality measurement results. [:ALL] returns measurement results in the following order: integrity, rho, frequency error, time error (in seconds), carrier feedthrough, phase error (in degrees), magnitude error, and EVM. For details, see Waveform Quality Measurement Results .

If the multi-measurement state is on, each result represents the average of a number of waveform quality measurements. Multi-measurement state, by default, is off. To set up multi-measurements, see SETup:DOWQuality:COUNt[:SNUMber] .

Instead of returning [:ALL] results, you may query the result for any particular measurement individually using the associated keyword, such as :RHO. If multi-measurement state is on, you may query the average, maximum, minimum or standard deviation for any particular measurement result individually by adding the :MAXimum, :MINimum or :SDEViation keyword.

Function

Queries the actual R-Data payload size (in bits) that the test set detects from the R-RRI channel (R-RRI channel carries the payload size and sub-packet identifier information) when measuring subtype 2 waveform quality. The R-Data payload size determines the modulation and walsh codes used on the R-Data channel. For details, see Waveform Quality Measurement Results .

If multi-measurement state is on, you may query the average, maximum, minimum or standard deviation for the payload size result by adding the :MAXimum, :MINimum or :SDEViation keyword. Multi-measurement state is off by default. To set up multi-measurements, see SETup:DOWQuality:COUNt[:SNUMber] .

Unlike most of other waveform quality measurement results (such as rho, frequency error, etc.), the payload size result can not be queried with FETCh:DOWQuality[:ALL]? command.

Programming Example

 
 
OUTPUT 714;"FETCh:DOWQuality:EVM:TRACe?" 

Function

These commands return code domain power measurement results for each of the reverse channels. The Subtype 0 reverse channels consist of the R-Pilot, R-RRI, R-DRC, R-ACK and R-Data and subtype 2 reverse channels consist of the R-Pilot, R-RRI, R-DRC, R-ACK, R-DSC, R-Aux Pilot and R-Data. So when measuring subtype 0 physical layer, querying R-Aux Pilot and R-DSC channels always returns 9.91E+37 (indicating not available).

The command for each channel returns 7 comma separated values, in the following order: modulation channel, Walsh code, spread factor, code domain power (dB), total code domain power (dB), normalized total code domain power (dB), and normalized total code domain power relative to R-Pilot (dB). See Code Domain Power Tabular Data for more information about these measurement results.

Note that when measuring subtype 2 R-Data channel with modulation type other than B4, the FETCh:DOWQuality:CDPower:DATA? command returns 7 comma separated values in the following order: modulation type, walsh code (9.91E+37), spread factor (9.91E+37), code domain power (9.91E+37), total code domain power (dB) of all walsh codes, normalized total code domain power (dB), and normalized total code domain power relative to R-Pilot (dB). The walsh code, spread factor and code domain power are always returned as 9.91E+37 (indicating not available) because the R-Data channel with modulation type other than B4 use more than one walsh channels (see Subtype 2 R-Data Packet Size, Modulation Type and Walsh Codes ). To determine the normalized total code domain power relative to R-Pilot for individual walsh channels that constitute R-Data channel, use FETCh:DOWQuality:CDPower:DATA[:REVerse]:RTPilot? .

If the multi-measurement state is on, the results are the average of a number of code domain power measurements. Multi-measurement state is off by default. To set up multi-measurements, see SETup:DOWQuality:COUNt[:SNUMber] .

Function

Queries the normalized total code domain power relative to R-Pilot for individual walsh channels that constitute R-Data channel. The R-Data channel can occupy up to 4 walsh channels (that is, 4 bins) depending upon the R-Data modulation type (see Subtype 2 R-Data Packet Size, Modulation Type and Walsh Codes ).

This query returns 5 comma separated values which are R-Data modulation channel/type followed by up to 4 power values (the normalized total code domain power relative to R-Pilot for individual walsh channels of R-Data, see Bin Delta Pilot (only available for subtype 2 physical layer R-Data channel) ). If R-Data consists of less than 4 walsh channels, 9.91 E+37 (NAN) results are returned for the remaining values.

• Modulation Channel or Type:
  • 0=I channel (indirectly indicating B4 modulation. This value is never returned because R-Data is allocated to Q channel for subtype 0 physical layer and for subtype 2 physical layer using B4 modulation)
  • 1=Q channel (indirectly indicating B4 modulation. This value is returned for R-Data channel for subtype 0 physical layer and for subtype 2 physical layer using B4 modulation)

  • 3 = Q2 modulation (only available for subtype 2 physical layer)
  • 4 = Q4Q2 modulation (only available for subtype 2 physical layer)
  • 5 = E4E2 modulation (only available for subtype 2 physical layer)
• 4 power values represent the following walsh channels based on the modulation type:
  • B4: power values returned for <Q:2 _SF=4 >, <NAN>, <NAN>, <NAN>
  • Q4: power values returned for <I:2 _SF=4 >, <Q:2 _SF=4 >, <NAN>, <NAN>
  • Q2: power values returned for <I:1 _SF=2 >, <Q:1 _SF=2 > , <NAN>, <NAN>
  • Q4Q2: power values returned for <I:2 _SF=4 >, <I:1 _SF=2 >, <Q:2 _SF=4 >, <Q:1 _SF=2 >
  • E4E2: power values returned for <I:2 _SF=4 >, <I:1 _SF=2 >, <Q:2 _SF=4 >, <Q:1 _SF=2

Function

Queries the subtype 2 physical layer code domain power + noise measurement results for all 32 bins on Q channel.

This query returns 128comma separated values. These represent 4 values for each of 32 bins. The 4 values returned for each bin are: Walsh code, spread factor, noise power (dB) and power (dB). See Code Domain Power + Noise Measurement Results Available Programmatically for more information about these measurement results.

There are frequently fewer than 32 bins with measurement data. For any unassigned bins (bins that don't contain measurement results), four 9.91 E+37 results are returned instead of data. This allows the query to always return 128 results regardless of how many bins contain measurement data. The FETCh:DOWQuality:CDPNoise:ICHannel:COUNt[:BIN]? command allows you to determine the total number of assigned bins (bins containing measurement results).

If the multi-measurement state is on, the results are the average of a number of code domain power measurements. Multi-measurement state is off by default. To set up multi-measurements, see SETup:DOWQuality:COUNt[:SNUMber] .
