For specified accuracy, allow the E5080A to warm up for a minimum of one
hour before running any S-Parameter tests.

In the PD1000A Control Software, select either the
On State S-Parameter

Control
(zero bias) tab.

a
Debug Mode:
Causes the system to send a SCPI
SYST:ERR?
command after
each command to identify any errors in the system measurements. Use the
IO Monitor
utility in the IO Libraries Suite to view the error messages.
b
Output Directory:
Lists the directory (folder) on the host PC to which the IV
and CV characterization data gets saved. Keysight’s PD1000A Control
Software uses the
EasyEXPERT
format and saves the IV and CV test data
with the Keysight IC-CAP Model Data Manager
**
file (*.mdm). There is no
default path or folder, so you must specify the path.
-- Click
Select
to choose a folder on the Host PC. For example, you might
create a folder such as:
PD1000AControl
.
Even though the PD1000A Bias Ts do
not
have a DC voltage
applied during off-state S-parameter tests, you may need to leave
them in the circuit being tested if the test fixture was calibrated
with the Bias Ts in place.
