Description
The product with the part number 778572-55 falls under the category of PXI Switches, specifically the model PXI-2555. This particular model is a PXI RF Multiplexer Switch Module, designed for sophisticated electronic test and measurement setups. It includes internal termination to prevent high-control reflections, making it an ideal choice for applications that require precise signal integrity, such as Video RF.
One of the key features of the PXI-2555 is its low insertion loss, low VSWR (Voltage Standing Wave Ratio), and high isolation, which are critical for maintaining signal quality in RF testing environments. Additionally, the module includes relay count tracking, allowing users to monitor the operational status and lifespan of the onboard relays.
The control logic is built directly onto the module, facilitating seamless relay operation without the need for external controllers. For complex test sequences, the PXI-2555 supports a scan list of up to 1024 instructions, which can be directly downloaded to the card. These instructions can be executed in either a single or continuous loop, providing flexibility for different testing requirements.
Enhancing its automation capabilities, the module features an outside trigger input for scan list advance, allowing external signals to control the test sequence progression. The trigger configuration is versatile, accepting signals via PXI TTL trigger lines, PXI star trigger, or software command. This makes the PXI-2555 compatible with a wide range of PXI chassis and external control setups. The module’s trigger input is sensitive to TTL voltage levels and is edge sensitive, with a minimum pulse width requirement of 70 ns, ensuring precise control over the timing of test sequences.
