Configurable test set (Option 015)
With the configurable test set option, front panel access
loops are provided to the signal path between the
source output and coupler input. 35 dB step attenua-
tors (5 dB steps) are also added in the receiver paths
of both ports. This capability provides the ability to
add components or other peripheral instruments for
a variety of measurement applications or to make
high dynamic range measurements with two-port
calibration.
High power measurement configuration
Add external power amplifier(s) between the source
output and coupler input to provide up to +30 dBm of
power at the test port(s). Full two-port error correc-
tion measurements possible. When the DUT output
is expected to be less than +30 dBm, measure directly
at the B input and use the internal step attenuators
to prevent damage to the receiver. For measurements
greater than +30 dBm, add external components such
as couplers, attenuators, and isolators.
Extended dynamic range configuration
Reverse the signal path in the coupler and bypass
the loss typically associated with the coupled arm.
Change the port 2 switch and coupler jumper config-
urations to increase the forward measurement
dynamic range up to 143 dB. When making full
two-port error corrected measurements, the reverse
measurement is degraded by 15 dB, with up to
113 dB of dynamic range available.
