8510XF Network Analyzer Systems 3-45

Operation

Alternative 1.0 mm Calibrations

Broadband TRM This is a method of calibrating across the entire frequency range of the

8510XF, using the Thru-Reﬂect-Match technique.

NOTE When this technique is used, the performance of the 8510XF is not speciﬁed.

Use broadband TRM calibration only in situations where saving time is

more important than insuring accuracy.

Broadband TRM

Standards

The broadband TRM calibration process is essentially the same as TRM

process already described under “TRL (TRM) 2-Port” on page 3-19:

{THRU} Connect Port 1 to Port 2 through a cable.

{S11 REFLECT

SHORT}

Connect a short to Port 1 (use offset short No. 1, male or

female, as appropriate).

{S22 REFLECT

SHORT}

Connect a short to Port 2 (use offset short No. 1, male or

female, as appropriate).

{ISOLATION

LOAD}

Connect isolation standards to Port 1 and Port 2. The

isolation standard is a broadband load, which consists of

a 50 GHz load (male or female, as appropriate) combined

with a lossy delay line from the 1.0 mm calibration kit

(male or female, as appropriate).

{LINE MATCH

MATCH}

Connect match standards to Port 1 and Port 2. The match

standard is a broadband load, which consists of a 50 GHz

load (male or female, as appropriate) combined with a

lossy delay line from the 1.0 mm calibration kit (male or

female, as appropriate).

{LOWBAND

REFLECT’N}

This standard is not used in connection with the 1.0 mm

calibration kit (for information regarding its use with

other calibration kits, see the manuals for those kits).
