As noted in the Power Menu Set descriptions below, the POWER menu and its related sub-menus vary in menu appearance, menu links, button presence, and button type (read/write vs. read-only) depending on a number of factors including:
• Type of sweep set
• Instrument model number
• Installed options
• Application receiver configuration mode
• Frequency range configured
Sweep Types
The instrument sweep type setting changes the POWER Menu Set depending on if the Sweep Type is set to
• Frequency-Based (Linear)
• Frequency-Based (Log)
• Segmented Sweep (either Frequency-Based or Index-Based)
• Power Sweep (either CW Freq or Swept Freq)
VNA Model, Option, and Mode
For MS4642A, MS4644A, and MS4645A VNAs, the POWER menu variants depend on the sweep type selected above and whether Multiple Source and mm-Wave are selected.
For MS4647A VNAs without Option 080/081, the POWER menu variants depend on the sweep type set above, and whether Multiple Source and BB/mm-Wave are selected.
For MS4647A VNAs, additional menu changes depend on the frequency range covered, the Receiver Configuration Mode if set to Modular Broadband or Modular Broadband with Multiple Source:
• Modular Broadband requires a MS4647A with Option 080/081 and an attached 3739x Test Set. Menus change depending the sweep type set above and the frequency range set, particularly depending on below, across, and above 54 GHz.
• Modular Broadband (a MS4647A with Option 081 and Option 061/062 providing attenuators) with Multiple Source can be configured. If at least one band is configured with a frequency greater than 54 GHz, an additional button is present.
