Triggers an application self-test. This command returns a 1 if all the tests passed and a 0 if one or more of the tests failed. Use [:SENSe]:APPLication:TST:RESult? to retrieve the detailed results of the test.

Shift 8 (System), Application Self Test

Retrieves the detailed results from the application self-test. [:SENSe]:APPLication:TST? must be called before this command to get correct results.

The response begins with an ASCII header. The header specifies the number of following bytes. It appears in the format #AX, where A is the number of digits in X, and X is the number of bytes that follow the header. There will be a total of 18 fields in the return string and will have the following format:

PASSED/FAILED, PASSED/FAILED, Int, Int, Int, Int¸ Int, Int, Int, Int, Int, Int, Int, PASSED/FAILED, Float, Float, Float, String.

The first PASSED/FAILED field represents the overall test result. The second field represents whether the signal generator is functioning properly. Fields 3 through 13 show the PLL status at the following frequencies:

500000 Hz, 160500000 Hz, 320500000 Hz, 480500000 Hz, 640500000 Hz, 800500000 Hz, 960500000 Hz, 1120500000 Hz, 1280500000 Hz, 1440500000 Hz, 1600000000 Hz

Field 18 shows the Level Cal version.

There are four PLLs that are tested on the signal generator and an integer from 0 to 15 is shown in each field. Each PLL represents one of the four bits in the integer number. Below is a description of the PLLs and the bits that they correspond to:

Bit 0: Sys PLL
Bit 1: IQ PLL
Bit 2: LO PLL
Bit 3: VR PLL

A 1 in the bit means that the PLL is functioning properly and a
0 means there is something wrong with the PLL. For example,
a value of 13 (1101) means that the IQ PLL has failed. Field fourteen describes whether the internal SINAD hardware test has passed or failed. The 3 floats following the PASSED/FAILED field are the SINAD level, SINAD frequency, and the SINAD peak to peak value.

Shift 8 (System), Application Self Test

Sets the number of times the numerical values in the TETRA Analyzer Summary window are averaged.

<integer>

1 to 25

1

To set averaging to 15:

Sets the receiver power offset. Please note that when Auto Rx Range is set to On, changing the offset value will cause the Ref Level to change. For example, if the reference level is at 7.0 dBm and the Rx power offset is then set to 10 dB external gain, the value of the refererence level will be automatically adjusted down to -3.0 dBm.

If Auto Rx Range is Off, any adjustments to the offset will be reflected in the vertical position of the spectrum trace. The reference level will not be adjusted.

The Received Pwr value in the Summary Table is also affected by changing this value.

The query returns a value from -100 to 100. A negative sign means external gain and no sign means external loss.

To set the external attenuation to 30 dB:

Sets the modulation type to Base Station (BS) or Mobile Station (MS). Please note that setting the modulation type will restart the sweep.

To set the modulation type to MS:

Sets the squelch power level. The squelch is only applied to the TETRA Analyzer Summary window on the front panel and will blank out (--) all summary measurements except for Received Pwr when the received power level is lower than the squelch power setting. FETCh:SIGAnalyzer?, READ:SIGAnalyzer?, and MEASure:SIGAnalyzer? will always return all numerical values.

The query will be returned in the units (dBm, Watts, or Volts) selected through the Rx Units button using the front panel or with the command: UNIT:POWer:RX. If the Rx Units has been set to dBm, the squelch setting is returned in dBm. If the unit is set to Watts, the squelch setting is returned in fW. If the unit is set to Volts, the squelch setting is returned in fV.

The set command is sent using the units selected with the Rx Units button on the front panel or with the command: UNIT:POWer:RX. If the Rx Units has been set to dBm, the squelch setting must be set in dBm. If the unit is set to watts, the squelch setting must be set in fW. If the unit is set to Volts, the squelch setting must be set in fV.

Turns off auto ranging and adjusts the receiver reference level once.
In TETRA Analyzer measurement, this command adjusts the receiver reference level of the spectrum graph.

To adjust range:

Turns auto range for the receiver on or off. When auto range is on, the reference level is automatically adjusted to the proper value to show the trace on the screen. If the auto ranging is turned off, the reference level will not adjust according to where the trace is. In TETRA Analyzer measurement, this command adjusts the reference level of the spectrum graph.
