Making Uncalibrated Measurements with the
NI 5632

Performing uncalibrated measurements with the NI 5632 can be useful for measuring device
raw performance, custom measurement configuration, and other specialized measurements.
You can perform uncalibrated measurements using the NI-VNA Soft Front Panel (SFP) or the
NI-VNA driver API.
1.

Prepare for the measurement.
a)

Warm up the device and the DUT as specified in the device specifications.

b)

Make signal connections as directed in the 

Connecting Signals

 section.

c)

Verify that the device is within the factory calibration interval.

2.

Set up an initial, uncalibrated measurement.
a)

Preset the NI 5632.

b)

Configure the source parameters, including reference frequency, output power, and
IF bandwidth.

c)

Connect the DUT to verify setup, cables, adapters, and operation.

d)

Select which S-parameter(s) to measure, and choose the display format.

3.

Start the measurement.

4.

Observe the uncalibrated response.

5.

Remove the DUT.

Calibrating the NI 5632

Frequent calibration is particularly important for the NI 5632 because it allows you to remove
certain errors from the actual measurements. Calibration removes errors caused by
