74 Agilent N8201A Performance Downconverter Synthetic Instrument Module, 250 kHz to 26.5 GHz
3 Auto Couple
Auto All
When Auto All is pressed, the N8201A automatically couples all instrument settings that
have auto and manual choices. In most cases, these auto settings give the most accurate
measurements and optimum dynamic range. When a function is coupled, it is in the Auto
state. When it is uncoupled it is in the Man state.
Key Path: Auto Couple
Dependencies/Couplings: When Auto All is selected:
• Resolution BW couples to: Span and Span/RBW
• Video BW couples to: Res BW and VBW/RBW
• Sweep Time couples to: Res BW; Video BW; Detector; Span and Center Frequency
• CF Step couples to: Span in swept spans, to Res BW in zero span
• Attenuation couples to: Ref Level; Ext Amp Gain; Atten Step; Max Mixer Lvl; and Int
Preamp
• FFT & Sweep couples to: Res BW and Span
• PhNoise Opt (phase noise optimization) couples to: Res BW; Span and FFT & Sweep
sweep type
• Detector couples to: marker functions; Avg/VBW Type; Average On Off; Max Hold and
Min Hold
• Average Type couples to: the marker functions; Detector and Scale Type
• ADC Dither couples to: Sweep Type; Span; Res BW; ADC Ranging and FFTs/Span
• VBW/RBW ratio is set to 1.0
• Span/RBW ratio is set to Auto
• Auto Sweep Time is set to Normal
• FFT & Sweep is set to Auto:Best Dynamic Range
• ADC Ranging is set to Autorange
• Marker Count, Gate Time is set to Auto
• Marker Trace and Printer have an Auto setting, but are not affected by Auto All.
Remote Command:
:COUPle ALL|NONE
:COUPle?
Remote Command Notes:
COUPle NONE sets all the functions to the manual (not coupled) mode. There is no
front-panel key equivalent to the COUPle NONE command.
