(Write-only) Aborts a source power calibration sweep that is in progress.

To use this ABORt command, you MUST use the ASYNchronous argument with SOUR:POW:CORR:COLL:ACQ

After aborting, this message appears in the error log: +243,"Requested operation was canceled".

Parameters

<ch>

Channel number of the source power cal. If unspecified, value is set to 1

<port>

Port number to correct for source power. If unspecified, value is set to 1.

Default

Not Applicable

Note: With PNA Rev. 6.2, a new "id" argument has been added to this command, replacing SOUR:POW:CORR:COLL:METH.

(Write-only) Initiates a source power cal acquisition sweep using the power sensor attached to the specified channel (A or B) on the power meter, using a USB power sensor, or using the specified PNA receiver.  

For source power cal, the power meter can NOT be controlled by the PNA using the GPIB Talker/Listener interface. Instead use one of the following methods:

• If present, use the GPIB dedicated controller port.

• Connect the power meter to the PNA using a USB / GPIB interface (Keysight 82357A).

• SCPI programming of the PNA using a LAN Client interface (see example).

• Send SCPI commands through the COM interface using the SCPI String Parser object.

• Directly control the Power Meter and PNA to step frequency; then acquire and store the Power reading. (see example).

• Configure the Power Meter/Sensor as a PMAR Device. Learn how. See SCPI commands.

Parameters

<ch>

Channel number of the source power cal. If unspecified, value is set to 1

<port>

Port number to correct for source power. If unspecified, value is set to 1.

<char>

Acquisition Choose from:

• PMETer - Power Meter is used for all readings.

• PMReceiver - Power meter for the first iteration; then use the reference receiver for remaining readings if necessary (same as "fast iteration" box checked on dialog box)

• RECeiver -  Use PNA measurement receiver for all readings.

<id>

String  (Not case sensitive). The power sensor or PNA receiver to use for measuring power.

For PMETer or PMRECeiver, choose from:

• "ASENSOR" or "BSENSOR". For U series USB sensors, always specify "ASENSOR"

For RECeiver, choose from:

• Any PNA receiver to acquire readings using physical or logical receiver notation.

• Any configured PMAR device name. Learn more about PMAR Devices. See PMAR commands.

[src]

Optional argument. String. (NOT case sensitive). Source port.  Use SOUR:CAT? to return a list of valid port names.

While this argument can be used to make settings for ALL ports, it is designed to access ports that are not simple numbers, such as "Port 1 Src2". Otherwise, the <port> argument performs the same function. If both arguments are specified, [src] takes priority.

[sync]

If this argument is specified, must also specify [src].

Choose from:

• SYNChronous - Blocks SCPI commands during standard measurement (default behavior).

• ASYNchronous - Does NOT block SCPI commands during standard measurement.

Default

Not Applicable

(Read-Write) This command, along with SOUR:POW:CORR:COLL:AVER:NTOLerance, allows for settling of the power sensor READINGS.

Note: This command is global and does not depend on a specific channel number.

Sets the maximum number of acquisitions that will be used to acquire one settled reading from the power meter.

This setting and corresponding SOUR:POW:CORR:COLL:AVER:NTOLerance command only effect the settled reading of the currently selected legacy power meter.

Note: To set the COUNT and NTOLerance of a specific PMAR, use the SYST:CONF:EDEV:PMAR:READ:COUNT and SYST:CONF:EDEV:PMAR:READ:NTOLerance commands.

Users may want to adjust this number if they know the signal is noisy as these settings set a threshold that determines when the power meter reading is done.

Each reading is averaged with the previous readings. When this average meets the Average:NTOLerance value or this number of readings has been made, the average is returned as the valid reading.

Parameters

<port>

If provided, this argument is ignored by the PNA.

<num>

Maximum number of readings to make to allow for settling. Choose any number between 3 and 1000.

Examples

Return Type

Numeric

Default

.050 dBm

(Read-Write)  Enables and disables the display of power readings on the PNA screen. Send this command BEFORE you begin a source power cal acquisition. After the source power cal data is acquired, this setting is reset to ON.

Parameters

<ch>

Channel number of the source power cal. If unspecified, value is set to 1

<port>

If provided, this argument is ignored by the PNA.

<ON|OFF>

ON (1)  Source power calibration dialog box is shown on the PNA screen. Power  readings are plotted against the Tolerance value as limit lines.

OFF (0) - Source power calibration dialog box is NOT shown on the PNA screen.

Examples

SOUR:POW:CORR:COLL:DISP ON
source1:power2:correction:collect:display:state off

Query Syntax

SOURce:POWer:CORRection:COLLect:DISPlay[:STATe]?

Return Type

Boolean (1 = ON, 0 = OFF)

Default

ON (1)

(Read-Write)  Enables and disables frequency checking of source power cal acquisition sweeps. ONLY use when you have more than one power sensor.

Parameters

<ch>

Channel number of the source power cal. If unspecified, value is set to 1

<port>

If provided, this argument is ignored by the PNA.

<ON|OFF>

ON (1) turns source power cal frequency checking ON. A requested acquisition will only succeed for those frequency points which fall within a frequency range specified for the power sensor being used. An acquisition will pause in mid-sweep if the frequency is about to exceed the maximum frequency limit specified for that sensor. When the sweep is paused in this manner, a sensor connected to the other channel input of the power meter can be connected to the measurement port in place of the previous sensor, and used to complete the sweep. However, the maximum frequency specified for the second sensor would need to be sufficient for the sweep to complete. Frequency limits are specified using the SOUR:POW:CORR:COLL:SEN command.

OFF (0) - turns source power cal frequency checking OFF. An acquisition will use just one power sensor for the entire sweep, regardless of frequency.

Examples

SOUR:POW:CORR:COLL:FCH ON
source1:power2:correction:collect:fcheck:state off

Query Syntax

SOURce:POWer:CORRection:COLLect:FCHeck[:STATe]?

Default

OFF (0)

(Read-Write) This command, along with SOUR:POW:CORR:COLL:ITER:NTOL control the number of settled readings taken to produce a single power point during source power cal.

The source power cal reads the power (performed by SOUR:POW:CORR:COLL:AVER:COUNT and SOUR:POW:CORR:COLL:AVER:NTOLerance) and makes internal adjustments to set the power to a desired level. These settings determine how many attempts (COUNt) the analyzer will make in an attempt to get close enough (NTOLerance) to the target power level.

Parameters

<ch>

Channel number of the source power cal. If unspecified, value is set to 1

<port>

If provided, this argument is ignored by the VNA.

<bool>

ON (or 1) -  enables SCPI error on source power calibration failure.

Examples

SOUR:POW:CORR:COLL:WARN ON
source1:power2:correction:collect:warn off

Query Syntax

SOURce:POWer:CORRection:COLLect:WARN?

Return Type

Boolean (1 = ON, 0 = OFF)

Default

OFF (0)

(Read-Write) Writes and reads source power calibration data.

The effect from this command on the channel is immediate. Do NOT send SOUR:POW:CORR:COLL:SAVE after this command as it may invalidate the uploaded data.

When querying source power calibration data, if no source power cal data exists for the specified channel and source port, then no data is returned.

If a change in the instrument state causes interpolation and/or extrapolation of the source power cal, the correction data associated with this command correspond to the new instrument state (interpolated and/or extrapolated data).

If the channel is sweeping the source backwards, then the first data point is the highest frequency value; the last data point is the lowest. Use the SENS:X:VALues? command to return the X-axis values in the displayed order.

Parameters

<ch>

Channel number of the source power cal. If unspecified, value is set to 1

<port>

Port number to correct for source power. If unspecified, value is set to 1.

<data>

Correction Data

[src]

String. (NOT case sensitive). Source port. Optional. Use SOUR:CAT? to return a list of valid port names.

While this argument can be used to make settings for ALL ports, it is designed to access ports that are not simple numbers, such as "Port 1 Src2". Otherwise, the <port> argument performs the same function. If both arguments are specified, [src] takes priority.

Examples

SOURce1:POWer2:CORRection:DATA 0.12, -0.34, 0.56

Query Syntax

SOURce<ch>:POWer<port>:CORRection:DATA? [src]

Return Type

Depends on FORMat:DATA command

Default

Not Applicable

(Read-Write) Writes and reads power correction values from the previous iteration of the source power cal. Data for which the first power meter reading were within the tolerance limit, the prior correction value is 0.

In all other respects, this command is the same as SOUR:POW:CORR:DATA.

This command can be used to determine the final power reading at each point of the power cal, for a cal that did not pass tolerance limits.  The formula for determining the power reading (in dB):

Power reading = Target power at the source port + specified power cal offset value + prior iteration corr value actual power corr value.

The "actual" value in this equation is returned with SOUR:POW:CORR:DATA?

Parameters

<ch>

Channel number of the source power cal. If unspecified, value is set to 1

<port>

Port number to correct for source power. If unspecified, value is set to 1.

<data>

Correction Data

[src]

String. (NOT case sensitive). Source port. Optional. Use SOUR:CAT? to return a list of valid port names.

While this argument can be used to make settings for ALL ports, it is designed to access ports that are not simple numbers, such as "Port 1 Src2". Otherwise, the <port> argument performs the same function. If both arguments are specified, [src] takes priority.

Examples

SOURce1:POWer2:CORRection:DATA:PRIor 0.12, -0.34, 0.56

Query Syntax

SOURce<ch>:POWer<port>:CORRection:DATA:PRIor? [src]

Return Type

Depends on FORMat:DATA command

Default

Not Applicable

(Read-Write) Specifies the power level that is expected at the desired reference plane (DUT input or output). This is not used for segment sweep with independent power levels or power sweeps.

Note: Although this command still works, it is recommended that you specify cal power by setting the test port power and offset value.

Parameters

<ch>

Channel number of the source power cal. If unspecified, value is set to 1

<port>

Port number to correct for source power. If unspecified, value is set to 1.

<num>

Cal power level in dBm. Because this could potentially be at the output of a device-under-test, no limits are placed on this value here. It is realistically limited by the specifications of the device (power sensor) that will be used for measuring the power. The power delivered to the PNA receiver must never exceed PNA specifications for the receiver!

[src]

String. (NOT case sensitive). Source port. Optional. Use SOUR:CAT? to return a list of valid port names.

While this argument can be used to make settings for ALL ports, it is designed to access ports that are not simple numbers, such as "Port 1 Src2". Otherwise, the <port> argument performs the same function. If both arguments are specified, [src] takes priority.

Examples

SOUR:POW:CORR:LEV 10
source1:power2:correction:level:amplitude 0 dbm

Query Syntax

SOURce:POWer:CORRection:LEVel[:AMPLitude]? [src]

Return Type

Numeric

Default

0 dBm

(Read-Write)  Sets or returns a power level offset from the PNA test port power. This can be a gain or loss value (in dB) to account for components you connect between the source and the reference plane of your measurement. For example, specify 10 dB to account for a 10 dB amplifier at the input of your DUT.

Cal power is the sum of the test port power setting and this offset value. Following the calibration, the PNA power readouts are adjusted to the cal power.

Parameters

<ch>

Channel number of the source power cal. If unspecified, value is set to 1

<port>

Port number to correct for source power. If unspecified, value is set to 1.

<num>

Gain or loss value in dB. Choose a value between -200 and 200

[src]

String. (NOT case sensitive). Source port. Optional. Use SOUR:CAT? to return a list of valid port names.

While this argument can be used to make settings for ALL ports, it is designed to access ports that are not simple numbers, such as "Port 1 Src2". Otherwise, the <port> argument performs the same function. If both arguments are specified, [src] takes priority.
