The measurement item list palette is displayed. Tap to select the items to measure/display.
If you select
“NA
,
”
that item will be hidden.
For details on each of the parameters, refer to
“4.6 Setting Spot Measurement”.
(Supplementary explanation)
The
V1
,
V2
,
V
, and
I
measurement items are the voltage and current amplitude values
measured by this instrument. The impedance and gain are calculated and displayed based
on these measurement values, but the
(V÷I)
and
Z
and the
(V1÷V2)
and
R
do not match
exactly because various error processing is performed inside this instrument. In particular,
please note that the difference between both of them will be extremely large when
open/short/load correction, port extension, and equalizing are performed.
■ [MEASURE TIME]
: Set the measurement time.
This sets the time per measurement. Increasing the time results in more measurement data
being averaged to reduce noise and obtain cleaner measurement results, but measurement
will become longer. For details on the averaging operation, refer to
“1.1 Setting Measurement
Time”
in
Instruction Manual (Advanced)
.
○ Setting procedure
<Numerical settings (immediate settings)>, <Numerical settings>
The setting range is 0 to 9,990 seconds and the setting resolution is 3 digits or 0.1 ms,
whichever is the largest. Even if 0 second is set, measurement is performed for a time
equivalent to 1 cycle of the measurement frequency (= 1 / frequency).
