PXI Modules

The PXI-1410 Preselector Module is a PXI 3U, 3-slot module that provides the necessary input signal conditioning and routing to form a complete RF PXI downconverter. When integrated with complementary modules, it enables down conversion over the 100 kHz to 26.5 GHz frequency range. The PXI-1410 employs a 70 dB (10 dB/step) input step attenuator that enables a dynamic range of approximately +30 dBm to -160 dBm. The module uses broadband switches to distribute the incoming RF signal to other PXI modules for further processing with minimal signal degradation. In addition, the module contains an electronically tuneable, 4-stage, YIG-tuned filter (YTF) based RF-input pre-selector, allowing for greater than 80 dB input image rejection and greater than 40 MHz of instantaneous input bandwidth. These attributes provide enough performance to satisfy even the most demanding spectrum analysis applications. For additional bandwidth (up to 350 MHz), the PXI-1410 offers a bypass path that automatically routes signals around the band limited preselector.

The PXI-1450B Local Oscillator Module is a PXI 3U, 2-slot synthesizer module intended for frequency down conversion applications. The PXI-1450B is a VCO-based, 3 to 9 GHz synthesizer capable of a tuning resolution of less than 1 Hz. It is optimized for speedy (1 ms) settling time to allow for fast frequency down conversion applications that employ Phase Matrix models PXI-1420 MW Downconverter Module (2.7 to 26.5 GHz) and PXI-1430B RF Downconverter Module (100 kHz to 2.9 GHz). The PXI-1450B contains all the circuitry necessary to lock the synthesizer and a 100 MHz ovenized crystal oscillator to an externally provided 10 MHz master reference oscillator. This capability enables the module to distribute its internal high-stability reference or the customer-provided external reference to other PXI modules within a PXI mainframe chassis.

The PXI-1440 IF Downconverter Module is a PXI 3U, 1-slot module that facilitates additional frequency translations to lower intermediate frequencies (IF) when high-dynamic range digitization is required. The module can receive multiple IF inputs from two different downconverter modules. The IF-input signals can either be bypassed and sent out in wideband mode or filtered and further down converted before being up routed to the appropriate alias filter for additional processing in the narrowband mode. The two input sources to this module are normally the IF signals from the RF Downconverter Module (PXI-1430B) or from the MW Downconverter Module (PXI-1420). Additionally, the PXI-1440 contains video-processing circuitry to enable video demodulation or IF video triggering implementation in a PXI downconverter system. Features and controls include: incoming signal routing, anti-alias filter routing, IF output routing, LO level indicator, and several signal-path options for testing.
