FFT Mode
4-9
X/Y ................................. This parameter sets the X and Y axis scales. The scales that can be selected vary
according to the current Function setting.
When the Function setting is Y-T, the settings are fixed to:
X axis: Time; Y axis: LIN.
When the Function setting is Linear, Power, P.S.D., Cross, or Transfer:
X axis: LIN. or LOG.; Y axis: LIN., LOG., or Phase
When the Function setting is Coherence, the settings are fixed to:
X axis: LIN; Y axis: LIN.
RMS ............................... The RMS parameter only requires setting when a zone's Function parameter is
Linear, Power, P.S.D., or Cross. RMS can be specified as On or Off.
CHECKPOINT
When RMS is specified as On, the Y axis is displayed as an RMS scale.
CH. A Calc., CH. B Calc.
............................. These parameters only require setting for channels where the Function parameter
has been set as Linear, Power, P.S.D., Cross, Transfer, or Coherence. Calculation
can be specified as Off, DIF., DDIF., INT., or DINT.
