Required Software
Calibrating the PXIe-5654 requires you to install the following package on the calibration
system:

Test Conditions
The following setup and environmental conditions are required to ensure the PXIe-5654 meets
published specifications.
• Keep cabling as short as possible. Long cables act as antennas, picking up extra noise that
can affect measurements.
• Verify that all connections to the PXIe-5654, including front panel connections and
screws, are secure.
• Maintain an ambient temperature of 23 °C ± 5 °C.
• Keep relative humidity between 10% and 90%, noncondensing.
• Allow a warm-up time of at least 30 minutes after the chassis is powered on. The warm-
up time ensures that the PXIe-5654 is at a stable operating temperature.
• In each verification procedure, insert a delay between configuring all instruments and
acquiring the measurement. This delay may need to be adjusted depending on the
instruments used but should always be at least 1,000 ms for the first iteration, 1,000 ms
when the power level changes, and 100 ms for each other iteration.
6| ni.com | PXIe-5654 Calibration Procedure

• Plug the chassis and the calibration instrument(s) into the same power strip to avoid
ground loops.
• Use an appropriate torque wrench to tighten all module RF connectors (SMA, 3.5 mm, or
K). NI recommends a 0.565 N · m (5 lb · in.) wrench for SMA connectors and a
0.90 N · m (8 lb · in.) wrench for 3.5 mm or K connectors.
• Connect the frequency reference source to the signal source analyzer REF IN back panel
connector using a BNC(m)-to-BNC(m) cable, and connect the signal source analyzer
REF OUT connector to the PXIe-5654 REF IN connector using a BNC(m)-to-SMA(m)
cable.
• Ensure that the PXI chassis fan speed is set to HIGH, that the fan filters, if present, are
clean, and that the empty slots contain filler panels. For more information about cooling,
refer to the Maintain Forced-Air Cooling Note to Users document available at ni.com/
manuals.
• Frequencies less than and equal to 10 GHz apply to the 10 GHz and 20 GHz PXIe-5654;
frequencies above 10 GHz apply only to the 20 GHz PXIe-5654.
Initial Setup
Refer to the PXIe-5654 Getting Started Guide for information about how to install the
software and the hardware and how to configure the device in Measurement & Automation
Explorer (MAX).
Test System Characterization
The following procedure characterizes the test equipment used during verification.
Zeroing and Calibrating the Power Sensor
1. Connect channel A of the power meter to the power sensor.
2. Zero and calibrate the power sensor using the built-in functions in the power meter.
As-Found and As-Left Limits
The as-found limits are the published specifications for the PXIe-5654. NI uses these limits to
determine whether the PXIe-5654 meets the specifications when it is received for calibration.
Use the as-found limits during initial verification.
The as-left calibration limits are equal to the published NI specifications for the PXIe-5654,
less guard bands for measurement uncertainty, temperature drift, and drift over time. NI uses
these limits to reduce the probability that the instrument will be outside the published
specification limits at the end of the calibration cycle. Use the as-left limits when performing
verification after adjustment.

Verification
The performance verification procedures assume that adequate traceable uncertainties are
available for the calibration references.
Before starting verification, make the following reference connections.
1. Connect the frequency reference source to the signal source analyzer REF IN back panel
connector using a BNC(m)-to-BNC(m) cable.
2. Connect the signal source analyzer REF OUT connector to the PXIe-5654 REF IN
connector using a BNC(m)-to-SMA(m) cable.
Verifying 10 MHz Reference Frequency Accuracy
This procedure verifies that the internal oven-controlled crystal oscillator (OCXO) is adjusted
for correct frequency accuracy.
1. Connect the PXIe-5654 REF OUT 10 MHz front panel connector to the signal source
analyzer RF input connector using the K(m)-to-K(m) cable as shown in the following
figure.

1. Connect the power sensor to the PXIe-5654 RF OUT front panel connector as shown in
the following figure.

2. Initialize a new external calibration session for the PXIe-5654.
3. Create a list of test frequencies using the following table.

Start Frequency (MHz) Stop Frequency (MHz) Frequency Step (MHz)
0.25 0.25 —
250 20,000 250
4. Configure the PXIe-5654 using the following settings:
• Frequency: Start Frequency from the list created in step 3.
• Automatic Thermal Correction: 0 (Disable)
• Coarse Amplitude DAC2: 65535
5. Initiate signal generation if this is the first iteration of running this procedure; otherwise
skip to step 6.
