 Network Analyzers using S4VNA software

The error correction status is indicated for each trace individually. There is also a general status of error correction for all traces of a channel.

General error correction status

The general error correction status for all S-parameter traces of a channel is indicated in the specific field on a channel status bar (See General error correction status table). For the channel status bar description, see Channel Status Bar.

Error correction is enabled. The stimulus settings are the same for the measurement and the calibration.

If the function is active for all traces black characters on a gray background.

If the function is active only for some of the traces (other traces are not calibrated) white characters on a red background.

C?

Error correction is enabled. The stimulus settings are not the same for the measurement and the calibration. Interpolation is applied.

C!

Error correction is enabled. The stimulus settings are not the same for the measurement and the calibration. Extrapolation is applied.

Off

Error correction is turned off.

For all traces. White characters on a red background.

---

No calibration data. No calibration was performed.

Trace error correction status

The error correction status for each individual trace is indicated in the trace status field (See table below). For trace status field description, see Trace Status Field.
