Softkey in the amplifier and measurement menus, suitable for power
measurements.
See “Making a Power Measurement using Broadband Detection” on
page 3-56 for an example power measurement.
Access Keys: or or
Hardkey in the SOURCE area. Sets the power level of the internal RF
source and turns it on and off. Also allows the setting of parameters for
a power sweep and the setting of the power level at preset.
Softkey in the menu. This softkey turns on a power sweep
mode that is used to characterize power-sensitive circuits. In this
mode, power is swept at a single frequency. The start- and stop-power
values are selectable under the key. This feature is
convenient for such measurements as gain compression or automatic
gain control (AGC) slope.
Power sweep is independent of level. Use this function with frequency
CW mode only.
The span of the swept power is limited to being equal to or within one
of the seven pre-defined power ranges.
Hardkey in the SYSTEM area. Displays softkeys that allow you to
choose between a factory preset state or a user-defined preset state.
See Chapter 11, “Factory Preset State and Memory Allocation,” for a
complete list of factory preset state default parameters. See
on page 8-96 for an explanation of a user-defined preset
state.
can also be used in the event that your analyzer system
locks up, or you receive an "Unrecoverable error." If this should
happen, cycle the power on the analyzer, and press the key
several times while the analyzer is booting up. (The key
must be pressed at least twice after you hear the double beep.) Then,
follow the on-screen instructions. This procedure clears all information
in non-volatile memory, including calibrations.
