accessible over HP-IB. To load correction arrays over HP-IB, the
correction arrays must be created in the controlling program and
then downloaded to the synthesizer. The corresponding SCPI array
creation and control commands are given after the description of this
feature.
The HP 8360 Series Synthesized Sweepers provide extremely flat
power to a test port, for testing power sensitive devices such as
amplifiers, mixers, diodes or detectors. The user flatness correction
feature of the synthesizer compensates for attenuation and power
variations created by components between the source and the test
device.
User flatness correction allows the digital correction of up to 801
frequency points (1601 points via HP-IB), in any frequency or sweep
mode (i.e. start/stop, CW, power sweep etc.). Using a power meter
to calibrate the measurement system as shown in Figure F-l, a table
of power level corrections is created for the frequencies where power
level variations or losses occur (see Figure
F-2).
These frequencies
may be sequential linear steps or arbitrarily spaced. To allow for the
correction of multiple test setups or frequency ranges, you may save
as many as eight different measurement setups (including correction
tables) in the internal storage registers of the synthesizer.
