DONE: 2-PORT CAL Completes the full 2-port calibration. The error coecients are computed and stored. The
correction menu is displayed with

??????????????????????????????????????
ONE P A TH 2-PORT Displays the series of menus used to perform a high-accuracy , two-port calibration without an
S-parameter test set. This calibration procedure eectively reduces directivity , source match, load
match, isolation, reection tracking, and transmission tracking errors in one direction only .
Isolation correction can be omitted for measurements of devices with limited dynamic range . (The
DUT must be manually reversed between sweeps to accomplish measurement of both input and
output responses .) The required standards are a SHORT , an OPEN, a THRU , and an
impedance-matched LO AD . The procedure for performing a one-path 2-port calibration is
described in the \P erforming a 1-P ath 2-P ort Calibration " in Chapter 7.
??????????????????????
REFLECT'N Start the reection calibration for full 2-port calibration and displays the menu that measures one
port standards for reection calibration.
?
???????????????????????
(S11): OPEN When the cal kit is a 7 mm or 3.5 mm cal kit this softkey measures the OPEN standard and then
the softkey label is underlined. Or , this softkey displays the open standard menu that selects an
OPEN standard and measures the standard when the cal kit is 50 or 75 type-N.
?????????????
SHORT When the cal kit is a 7 mm or 3.5 mm cal kit this softkey measures the SHORT standard and then
the softkey label is underlined. Or , this softkey displays the short standard menu that selects a
SHORT standard and measures the standard when the cal kit is 50 or 75 type-N.
????????????
LO AD When the cal kit is a 7 mm or 3.5 mm cal kit this softkey measures the LO AD standard and then
the softkey label is underlined. Or , this softkey displays the load standard menu that selects a
load standard and measures the standard when the cal kit is 50 or 75 type-N.
????????????????????????????????????
REFLECT'N DONE Completes the reection calibration for the one-path 2-port calibration. The error coecients are
computed and stored. One-path 2-P ort menu is displayed, with the
??????????????????????
REFLECT'N softkey
underlined. If this key is pressed without measuring all the required standards , the message
CA UTION:ADDITIONAL ST AND ARDS NEEDED is displayed.
??????????????????????????????
TRANS-MISSION Starts the transmission calibration and displays the menu that measures frequency response and
load match for transmission calibration.
?
????????????????????????????????????????
FWD . TRANS. THRU Measures S
21
frequency response , and then the softkey is underlined. If the cal kit is user kit and
two or more standards are assigned to the forward transmission class , this softkey displays the
THRU standard menu that selects the THRU standard and measures it.
????????????????????????????????????????
FWD . MA TCH THRU Measures S
11
load match, and then the softkey is underlined. If the cal kit is user kit and two or
more standards are assigned to the forward match class , this softkey displays the THRU standard
menu that selects the THRU standard and measures it.
?????????????????????????????
TRANS. DONE Completes transmission calibration. The error coecients are calculated and stored. The one-path,
2-P ort menu is displayed, with the
? ????????????????????????????
TRANSMISSION softkey underlined. If this key is pressed
without measuring all the required standards , the message CA UTION:ADDITIONAL ST AND ARDS
NEEDED is displayed.
?????????????????????
ISOLA TION Starts the isolation calibration and displays the menu that measures isolation.
? ????????????????????????????????
OMIT ISOLA TION Omits correction for isolation from the calibration when it is not required.
????????????????????????????????????????????????
FWD .ISOL'N ISOL'N STD Measures S
21
isolation and then the softkey label is underlined.
?
??????????????????????????????????????????????
REV .ISOL'N ISOL'N STD Measures S
12
isolation and then the softkey label is underlined.
???????????????????????????????????
ISOLA TION DONE Completes isolation calibration. The error coecients are calculated and stored. One-path 2-port
menu is displayed, with the
?????????????????????
ISOLA TION softkey underlined. If this key is pressed without
measuring all the required standards , the message CA UTION:ADDITIONAL ST AND ARDS NEEDED
is displayed.
? ???????????????????????????????????????
DONE: 2-PORT CAL Completes the one-path 2-port calibration. The error coecients are computed and stored. The
correction menu is displayed with
?
?????????????????????????????????
CORRECTION ON , and the notation C2 is displayed at the left
of the screen. If this key is pressed without measuring all the required standards , the message
CA UTION:ADDITIONAL ST AND ARDS NEEDED is displayed.
