Critical Note: CALCulate commands act on the selected measurement. You can select one measurement for each channel using Calc:Par:MNUM or Calc:Par:Select. Learn more.
Applicable Models: N522xB, N523xB, N524xB (Write-Read) Sets and returns the display type for uncertainties for the selected measurement trace. |
|
Parameters |
|
<ch> |
Channel number of the measurement to display uncertainties. If unspecified, value is set to 1. |
<char> |
Display type. Choose from: NONE - Display the trace without uncertainties. MAXimum – Display the trace as the uncertainty maximum (measured or memory data + upper limit uncertainty values). Not supported with Smith Chart or Polar display format. MINimum - Display the trace as the uncertainty minimum (measured or memory data - lower limit uncertainty values). Not supported with Smith Chart or Polar display format. BAR – Display the uncertainties as “error bars” around the trace. Not supported with Smith Chart or Polar display format. SHADe – Display the uncertainties as a shaded region around the trace. Not supported with Smith Chart or Polar display format. ELLipse – Display the uncertainties in ellipse form. Supported only in Smith Chart or Polar display format. |

|
Parameters |
|
<ch> |
Channel number of the uncertainty measurement. If unspecified, value is set to 1. |
<"x,y,z"> |
String Comma or space delimited port numbers for which data is requested, enclosed in quotes. |
<filename> |
String Path, filename, and suffix of location to store the uncertainty data, enclosed in quotes. The suffix is not checked for accuracy.
