"I/Q-Vector"

Displays the captured samples in an I/Q-plot. The samples are con-
nected by a line.

"Real/Imag
(I/Q)"

Displays the I and Q values in separate diagrams.

Remote command:

CALCulate<n>:FORMat

C/N, C/No ← I/Q Analyzer

Opens a submenu to configure the carrier/noise ratio measurement. Measurements
without (C/N) and measurements with reference to the bandwidth (C/No) are possible.
