Multi-Port Full Duplex RF Communications Test Set
This document lists specifications for the NI Wireless Test System (WTS), manufacturing
number NI-MCT001. The WTS is a communications test set with full duplex RF ports capable
of both receiving and generating signals. You can use each RF port with integrated signal
analyzer and signal generator components, which have up to 200 MHz of instantaneous
bandwidth. The number of available signal analyzers and signal generators depends on the
selected system model.

Caution The protection provided by this product may be impaired if it is used in a
manner not described in this document.
This document uses the following terms:
•
Signal Analyzer (SA) refers to the receive signal paths at the PORT <0..n> front panel
connections.

connections.
Specifications are warranted by design and under the following conditions, unless otherwise
noted:
•
30 minutes warm-up time
•
Calibration cycle maintained
•
Chassis fan speed set to High
Specifications assume the WTS is configured to use the internal Reference Clock source,
unless otherwise noted.
Note Within the specifications, self-calibration °C refers to the temperature of the
last successful self-calibration of the signal analyzer or signal generator connected to
the port in use.
Specifications describe the warranted, traceable product performance over ambient
temperature ranges of 0 °C to 50 °C, unless otherwise noted.
Typical values describe useful product performance beyond specifications that are not covered
by warranty and do not include guardbands for measurement uncertainty or drift. Typical
values may not be verified on all units shipped from the factory. Unless otherwise noted,
typical values cover the expected performance of units over ambient temperature ranges of
23 °C ± 5 °C with a 90% confidence level, based on measurements taken during development
or production.
2σ specifications describe the 95th percentile values in which 95% of the cases are met with a
95% confidence for any ambient temperature of 23 °C ± 5 °C
Nominal values (or supplemental information) describe additional information about the
product that may be useful, including expected performance that is not covered under
Specifications or Typical values. Nominal values are not covered by warranty.
Specifications are subject to change without notice. For the most recent WTS specifications,

Electromagnetic Compatibility Guidelines
This product was tested and complies with the regulatory requirements and limits for
electromagnetic compatibility (EMC) stated in the product specifications. These requirements
and limits provide reasonable protection against harmful interference when the product is
operated in the intended operational electromagnetic environment.
This product is intended for use in industrial locations. However, harmful interference may
occur in some installations, when the product is connected to a peripheral device or test object,
or if the product is used in residential or commercial areas. To minimize interference with
radio and television reception and prevent unacceptable performance degradation, install and
use this product in strict accordance with the instructions in the product documentation.
Furthermore, any changes or modifications to the product not expressly approved by National
Instruments could void your authority to operate it under your local regulatory rules.
Caution To ensure the specified EMC performance, operate this product only with
shielded cables and accessories.
Caution To ensure the specified EMC performance, the length of any cable
connected to the Monitor, REF IN, REF OUT, CAL OUT, and Port <0..n>

Channel and Port Configuration
All ports can be configured to perform measurement analysis. The software will route the port
to a signal analyzer when in use and will terminate the port when not in use. When not in use,
the RF port is internally terminated to improve channel-to-channel isolation.
You can configure signal generation for broadcast on up to four channels simultaneously. RF
ports <0..3> and <4..7> support broadcast generation. The integrated signal generator(s) can
drive each group of four channels, as shown in the following figure.

Frequency response specifications are valid within any given frequency range, not the LO
frequency itself.
This specification describes the maximum residual sideband image within a 200 MHz
bandwidth at a given RF center frequency. Bandwidth is restricted to 20 MHz for LO
frequencies ≤ 109 MHz and restricted to 80 MHz for frequencies >109 MHz to 200 MHz.
This specification is valid only when the system is operating within the specified ambient
temperature range and within the specified range from the last self-calibration temperature,
as measured with the onboard temperature sensors.
For optimal performance, NI recommends running self-calibration when the WTS
temperature drifts ± 5 °C from the temperature at the last self-calibration. For temperature
changes >± 5 °C from self-calibration, residual image suppression is -40 dBc.

For optimal performance, NI recommends running self-calibration when the WTS
temperature drifts ± 5 °C from the temperature at the last self-calibration. For temperature

This specification describes the maximum residual sideband image within a 200 MHz
bandwidth at a given RF center frequency. Bandwidth is restricted to 20 MHz for LO
frequencies ≤109 MHz.
This specification is valid only when the system is operating within the specified ambient
temperature range and within the specified range from the last self-calibration temperature,
as measured with the onboard temperature sensors.
For optimal performance, NI recommends running self-calibration when the system
temperature drifts ± 5 °C from the temperature at the last self-calibration. For temperature

Self-Calibration
Self-calibration adjusts the WTS for variations in the environment using an onboard highprecision calibration tone. Perform a complete self-calibration after first setting up your WTS
and letting it warm up for 30 minutes.
Note Warm up begins when the PXI Express has been powered on and the
operating system has completely loaded.
The WTS is calibrated at the factory; however, you should perform a self-calibration in any of
the following situations:
•
After first setting up the WTS.
•
When the system is in an environment where the ambient temperature varies or the WTS
temperature has drifted more than ±2 °C from the temperature at the last self-calibration.
•
To periodically adjust for small performance drifts that occur with product aging.
NI recommends you perform self-calibration by sending the *CAL SCPI command.
Note Self-calibration may take up to 10 minutes to complete.
