Applicable Models: All excepts M937xA, P937xA (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. These settings affect every use of the power meter (PMAR and source power cal). 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/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 |

|
<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. |
|
<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. |

Applicable Models: All excepts M937xA, P937xA (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. |

This property affects error reporting during the acquisition of a source power calibration.

When those limits fail and SOUR:POW:CORR:COLL:WARN is set to OFF, the failure is not reported. This is the default.

Applicable Models: All (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. |

Applicable Models: All excepts M937xA, P937xA (Read-Write) Sets or returns a power level offset from the VNA 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 VNA 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. |

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. |
|
<bool> |
ON (or 1) turns source power correction ON. OFF (or 0) - turns source power correction OFF. |
|
[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. |
