PXI‑2546 | 2.7 GHz Dual 4×1 PXI RF Multiplexer Switch Module

PN：778572-46
The PXI‑2546 is a single-slot 3U PXI radio frequency multiplexer built with two independent latching SP4T relay banks (dual 4×1 multiplexer topology), designed for parallel RF stimulus-response measurement in wireless device, RF component and semiconductor automated test benches. It adopts latching electromechanical relays to cut steady power consumption and maintain channel state after power loss.

Core Hardware Specifications

  • Topology: Dual independent 4-to-1 SP4T multiplexer, two separate signal banks for parallel testing
  • RF Performance: Max bandwidth 2.7 GHz, characteristic impedance 50 Ω, max insertion loss -1.35 dB, high channel isolation
  • Relay Type: Latching electromechanical relay, low continuous power draw, retains switch state without holding current
  • Front I/O: 10 gold-plated female SMA jacks, standard RF coaxial interface
  • Built-in Monitoring: Onboard relay actuation counter to predict relay service life and avoid unplanned downtime
  • Synchronization: Native PXI hardware trigger bus for synchronous channel switching with digitizers, signal generators
  • Electrical Rating: Max switching voltage 30 V AC/DC, single-slot power consumption only 4 W
  • Environment: Operating temperature 0–55 ℃, indoor bench and rack-mounted PXI chassis compatible

Core Functional Advantages

  1. Dual independent 4×1 mux architecture enables two parallel RF test paths simultaneously, greatly improving mass-production test throughput.
  2. Latching relays eliminate continuous holding power consumption, reducing module heat and extending chassis service life for long unattended screening.
  3. Premium RF electrical metrics (low insertion loss, high isolation) minimize signal distortion, guarantee accurate RF power and S-parameter measurement.
  4. Built-in relay count tracking monitors switching cycles, supporting predictive maintenance and reducing unexpected equipment downtime.
  5. Full NI-Switch driver support, seamless integration with LabVIEW, TestStand, RFmx and signal generation/analysis instruments for unified RF ATE workflow.

Software Compatibility

Supports Windows 10/11 64-bit; fully compatible with LabVIEW, TestStand, NI-Switch driver, NI-RFmx, NI-VISA; provides C/C++, Python, C# programming APIs and InstrumentStudio soft panel.

Typical Applications

Wireless Bluetooth/Wi-Fi IoT module parallel RF performance test, RF filter/antenna component parameter characterization, semiconductor RF chip mass-production screening, consumer radio transceiver automated calibration, aerospace short-range RF signal switching measurement systems.
