Creating User Flatness Arrays
Creating a user flatness array for use in a scalar analysis measurement
To set up the sweeper
1. Connect equipment as shown in Figure 5-2. Do not connect the power
sensor to the system yet.
2. Press (PRESET) on the scalar analyzer (HP 8757).
3. If a frequency range other than the full range of the instrument is desired,
use the m and CsTopl keys on the sweeper to input the desired
frequency range.
4. If external cables and/or devices are used between the sweeper leveling
point (the RF OUTPUT if interrmlly leveled, or the coupler/splitter output
if externally leveled) and the remote test port, the nominal (average) loss
of these components should be entered as an offset. To enter the power
offset, press @iYWj OFFSET (in the POWER key group) and then enter the
nominal loss from the leveling point of the sweeper to the test port. (For
example, if there is a 6 dB loss from the leveling point to the remote test
port, enter a power offset of +6 dB.)
5. Set the power level to the level desired at the tat port by pressing
(POWER LEVEL] and entering the desired number.
6. Select @iiF] SPECIAL (12) (HZ/S/ENTER_). Use the Q) @Jj keys to select
the type of power meter you will be using. (437B for this example.)
7. Select (SHIFT) SPECfAL @ (Hz/s/ENTER_). Enter the HP-R3 address of the
power meter you will be using for the calibration. (Thirteen is the default
address for power meters.)
To set up the analyzer

1. On the analyzer, set up the appropriate measurement (i.e. gain for an
amplifier). Calibrate the measurement (thru and short/open calibration).
Press m (iJ on the analyzer to store the analyzer configuration and
sweeper parameters in storage register 1.
