Single Point Gamma
Single Point Gamma correction is used when you have a known and constant
frequency, so a single Gamma value can be used for calculation. The value for
Γ
DUT
may be entered as a Single Point Gamma which may be applied across all
measurement frequencies in the U2020 X-Series operating range. You may input
the value for GDUT directly into the U2020 X-Series via SCPI commands in the
magnitude-phase format.
Table-Based Gamma
Table-Based Gamma is used when there are multiple known frequencies, leading
to multiple Gamma values. This option supports a list of up to 1024 measurement
frequency values. You may load the values in table form directly into the U2020
X-Series via SCPI commands as a Gamma table to be used for calculation.
The Γ
L
values for factory calibration frequencies within the U2020 X-Series
operating range are already pre-loaded in the U2020 X-Series. These Γ
L
values
are retained across reset and power cycles.
NOTE
The U2020 X-Series supports up to 10 Gamma tables that are retained across
reset and power cycles.
NOTE
–The *OPT? query will return the option string “GAM” for U2020 X-Series
power sensors that have been pre-loaded with Γ
L
values. U2020 X-Series
power sensors that were shipped before the introduction of Gamma
correction have no pre-loaded Γ
L
values.
– For more details on SCPI commands, refer to the U2020 X-Series
Programming Guide.
