Overview
The Vector Signal Transceiver (VST) is an essential building block in RF communications test solutions supplied by
Cobham. Comprised of a vector signal generator and vector signal analyser the vector signal transceiver combines
multiple instruments into a single PXI Express module with the performance, flexibility and speed at low cost, and small
form factor required of a manufacturing test system.
Software Analysis/Generation (optional)
The VST is a software-designed instrument with
software analysis and generation packages for
the latest cellular, connectivity & IoT standards.
Expanded Bandwidth (option 02)
The VST module provides an industry leading
200 MHz of RF bandwidth leveraging the speed
and flexibility of the user programmable FPGA.
The added bandwidth enables the user to test
the latest options added to the leading wireless
and cellular standards including 802.11ac 160
MHz and LTE-A carrier aggregation while also
leveraging the latest performance enhancing
processing techniques such as digital predistortion.
Baseband I/Q Interface (option 03)
The VST can be configured with highperformance, differential or single-ended
baseband I/Q interface with 16-bit data sampled
at 120 MS/s, for a total of 80 MHz of complex
equalized I/Q bandwidth. This baseband I/Q
interface allows the VST to address many
additional applications, such as testing both the
up-converted RF and down-converted baseband signals of a device with a single instrument.

The VST features a zero-IF receiver enabling higher bandwidth, lower cost, less power consumption, and a smaller
footprint when compared to heterodyne receivers. Other advantages include simpler designs with single LOs, and high
selectivity, which allows separation of adjacent channels whose signals overlap.
The VST offers industry-leading performance and measurement speed. Using IEEE 802.11ac as an example, the VST
achieves an error vector magnitude (EVM) measurement floor of better than -45 dB (0.5 %) at 5.8 GHz for an 80 MHz
MCS9 signal.

Options for various radio communications standards are supported, ideal for
measuring transmitters, receivers and RF component performance in accordance
with methods defined in 3GPP / 3GPP2 and ETSI standards.
Waveform generation is supported using IQCreator™. IQCreator supports all
cellular and wireless connectivity standards and can be downloaded from the
Cobham Wireless website. A runtime license is all that is required to load and
play IQCreator waveforms using the VST.
Production test sequencing is supported using PXI Maestro application software.
PXI Maestro provides a turnkey solution using the VST, supplemented with any
Cobham 3060 series RF Combiner module to provide duplex connection to radio
transceiver antennas.
