Set up this instrument and perform measurement in the following order.
1) Set the measurement mode to IMPD−EXT in the
[Mode]
menu.
2) Reset the settings and then connect equipment and DUT.
3) Tap
[SETUP]
or press the
SETUP
key and then change each setting item as necessary.
[DISPLAY MODE Y]
: Set the graph Y-axis item.
[SWEEP ITEM]
: Set the sweep item.
[SWEEP UPPER]
: Set the sweep upper limit.
[SWEEP LOWER]
: Set the sweep lower limit.
4) The initial settings are 1 Vrms for the measurement signal amplitude, 0 V for the DC bias,
and 1.0 for the DUT drive amplifier gain. If you wish to measure with a different signal
amplitude or use a DUT drive amplifier, tap the
[OSC]
menu and change the settings.
[AMPLITUDE]
: Set the measurement signal amplitude.
[DC BIAS]
: Set the DC bias.
[POWER AMP GAIN]
: Set the DUT drive amplifier gain.
5) Set the conversion coefficient of the voltage probe, current detection resistor, current
probe, etc. Set the following items in the [
Range
] menu.
[WTG FAC PORT1]
: Set the reciprocal of the conversion ratio of the voltage probe.
[WTG FAC PORT2]
: Set the reciprocal of the current-voltage conversion ratio.
6) Press the
AC/DC ON
key to turn measurement signal output on.
7) Press the
MEASURE DOWN
key to perform down-sweep measurement and then wait for
the sweep to end. The following shows an example of when a frequency sweep was
performed.
8) Operating the knob moves a marker on the measurement data. This allows you to read the
measurement value at any frequency. You can also perform operations such as detecting
the maximum value, searching, and finding the location of an arbitrary gain value. For
more details on the operations, refer to
“1.7 Marker Operations”
in
Instruction Manual
(Advanced)
.
Performing open correction, short correction, and load correction enables measurement for
which the errors of the measurement system are corrected. For details on these correction
procedures, refer to
“1.8 Error Correction”
in
Instruction Manual (Advanced)
