76 Agilent N8201A Performance Downconverter Synthetic Instrument Module, 250 kHz to 26.5 GHz
3 Auto Couple
FFT & Sweep
Selects the FFT vs. Sweep key functions.
FFT “sweeps” should not be used when making EMI measurements. When an EMI detector
is selected, Manual:FFT is grayed out. If Manual:FFT is selected first, the EMI detectors are
grayed out.
Key Path: Auto Couple
Remote Command:
[:SENSe]:SWEep:TYPE AUTO|FFT|SWEep
Changes the sweep type to FFT or swept, or it lets the N8201A automatically choose the
type of analysis to use based on current instrument settings.
[:SENSe]:SWEep:TYPE?
Example:
SWE:TYPE FFT
Auto: Best Dynamic Range
This function is automatically activated when Auto All is selected. Selecting Auto: Best
Dynamic Range tells the N8201A to choose between swept and FFT analysis, with a primary
goal of optimizing the dynamic range. If the dynamic range is very close between swept and
FFT, then it chooses the faster one.
While Zero Span is selected, this key is grayed out. The status of the FFT & Swept selection
is saved when entering zero span and is restored when leaving zero span.
Key Path: Auto Couple, FFT & Sweep
Saved State: Saved in Instrument State
Remote Command:
[:SENSe]:SWEep:TYPE:AUTO:RULes SPEed|DRANge
Selects the rules to use when SWE:TYPE AUTO is selected. This setting, combined with
your current N8201A setup, is used to select either FFT or swept mode.
[:SENSe]:SWEep:TYPE:AUTO:RULes?
Example:
SWEep:TYPE AUTO selects the automatic mode.
