:CHANnel:PROBe:CORRection:RESPonse

Command Syntax

:CHANnelN:PROBe:CORRection:RESPonse {TVIew | SESTimate}

Where N identifies a specific channel in the form "<connection1-8>_<ch1-8>". With connection 1, the connection number part (that is, "1_") is optional, and you can simply use the channel number "<ch1-8>". For example, connection 4 channel 2 is CHANnel4_2.

Description

Specifies the probe correction response:

• TVIew — (True View: Vout/Vin) Characterizes the output of the probe as a function of the input at the probe tips. Defining the response this way lets you evaluate the probe's accuracy in reproducing the actual signal present in your system with the probe attached. This correction is what you would see with a real band-limited probe that has finite input impedance.

  The oscilloscope corrects the “Vout/Vin” response to be flat with frequency and phase to your defined bandwidth limit. It does not de-embed the loading effects of the probe.

  Keysight's probe corrections are typically defined using Vout/Vin.

• SESTimate — (Source Estimate: Vout/Vincident = Vout/Vsrc) This method corrects the probe as “what would be there if the probe were not present”.

  One drawback of defining the probe’s response in this manner is that if the probe’s loading causes your circuit to lose some timing or amplitude margin, you probably want to know that when you make a measurement. Vout/Vsrc compensation will hide these effects from you.

  However, this method can be effective if probing at the transmitter.

  When Vout/Vsrc is selected, the system source impedance is 25 Ohms.

  This mode is available with the MX0020A/21A/22A/24A/25A probe amplifiers.
