Operating Notes
Important changes caused by using "Factory Preset" to the desired mm-wave
instrument state are as follows:
SWEEP MODE
SET Z
0
WAVEGUIDE DELAY
WAVEGUIDE CUTOFF
SOURCE #1 POWER and SOURCE #2
POWER
After factory preset, the operator must recall an appropriate mm-wave
instrument state previously saved. This is usually instrument State 8.
The RF signal source power is set to a nominal value by the system
configuration software. If needed, adjust the level for your application. For
maximum measurement accuracy, calibrate the system with the same source
power as to be used during the measurement. RF source power is adjusted by
pressing the keys in the Stimulus [
If the network analyzer displays
source power.
2-12 HP 85106D mm-Wave System
Factory preset selects step sweep mode.
The mm-wave system operates in Step,
Single Point, or Frequency List sweep
modes only.
Factory preset selects 50; the mm-wave
system uses 1.
Factory preset selects the coaxial
configuration. For mm-wave measurements,
select the waveguide configuration.
This function defines the waveguide cutoff
frequency, f used in the electrical delay
co
computation. Factory preset selects 0 Hz.
Power levels defined in the standard
instrument state depend on the source and
waveguide frequency band; the levels
should be close to those listed in the
sections titled "RF Signal Power Control"
and "LO Signal Power Control," and Table
on page 2-14.
