Calibration Procedure
NOTE The following procedure assumes that the 1.0 mm calibration kit (85059A)
will be used to calibrate the 8510XF.
Load Calibration
Constants
Before you can calibrate the system, you must load the appropriate
calibration constants into the system.
1. Insert the calibration data disk (included with the 1.0 mm calibration kit)
into the 8510C disk drive.
2. Press
[DISC] {LOAD}.
The analyzer displays
SELECT DATA TYPE TO LOAD.
3. Select
{CAL KIT 1} or {CAL KIT 2}.
The analyzer displays
USE KNOB OR STEP KEYS TO SELECT A FILE.
4. Select
CK_1MMA1A from the display menu.
(This file is the recommended choice for normal operation; the other file,
CK_1MMA1B, is discussed under “Broadband Standards” on page 3-43).
5. Select
{LOAD FILE}. This loads the calibration constants into the memory
of the network analyzer. A screen message indicates when the load
process is complete (

6. Remove the disk from the drive.
Set Up the Analyzer 1. Set the desired frequency range for the calibration, using the STIMULUS
keys.
2. Select step mode, using

5. Be sure that the system impedance is set to 50
Ω, by pressing:
[CAL] {MORE} {SET Z0}
(If the display does not read 50.0Ω, press: [5] [0] [X1].)
