Service manual

The 8510XF requires separate verifications for frequencies below
and above 50 GHz (see "Frequency Ranges" in this same chapter).
A special two-band calibration procedure is required for the
performance verification of the 8510XF System (a single full-band
measurement calibration is equivalent).not
There are up to three different full 2-port calibrations and
corresponding frequency ranges required, which are stored
in suggested locations in the 8510 analyzer.

1. SOLT = Short, Open, Load and Thru standards
2. The broadband load is a combination of a lossy delay line plus a 50 GHz load.
3. Also used for 45 MHz frequency point.

1. This calibration is for Option 005 systems only.
2. The frequency for standard systems is 2–50 GHz.
3. The frequency range shown is for the E7352A system only.
The E7342A system's frequency range will be: 50–85 GHz

Calibration Techniques:
A variety of calibration techniques can be used with the 8510XF, including the following:
(Short-Open-Load-Thru) Used for performance verification 45 MHz to 50 GHz.
(Shorts with different offset lengths) Used for performance verification 50 GHz
to 110 GHz.
(Thru-Reflect-Line)**
(Thru-Reflect-Match)**
** Note: Not used for performance verification
The calibration technique used depends in part on the type of calibration kit used. The 1.0 mm
calibration kit (85059A) was designed specifically for the 8510XF, and uses a combination of
two calibration techniques: SOLT calibration for frequencies up to 50 GHz, and offset shorts
calibration for frequencies above 50 GHz. This combination of techniques provides the best
possible calibration results on the 8510XF.

50 GHz Load
Lossy Delay Line
"FWD/REV ISOL'N LOAD"
For: > 50 GHz a lossy delay line is required in addition
to a 50 GHz load.*
For: < 50 GHz use a 50 GHz load only.
Note: If you use a 50 GHz load only, a bad calibration will
result due to reflection from the load above 50 GHz.

or more information refer to the section on "Frequency Ranges"
in this same chapter. The parameters for these calibrations are set up
automatically on the analyzer by the performance verification software.
Clarifying Connector Sex:
The calibration standard labels that appear in the 8510XF softkey
calibration menus specify connector sex as "(M)" or "(F)". The sex designator
refers to the sex of the test port connector to which the calibration standard
is connected ( the sex of the calibration standard connector).not
Offset Shorts:
Offset shorts are used in the place of opens and loads
The "OPEN" category is therefore renamed "OPEN/SHORT," and the "LOAD"
category is renamed "LOAD/SHORT" on the calibration menu softkey labels.
