National Instruments 778793-01 PXI RF Multiplexer Switch Module
The part number 778793-01 from National Instruments is the identifying part number for the PXI-2593 PXI RF Multiplexer Switch Module. This module has a maximum switching voltage of 150 V, CAT I (channel-to-channel and channel-to-ground). The maximum switching current (per channel) is 0.5 Amperes while the maximum carry current (per channel) is 1 Amperes. Up to 2 channels can be used simultaneously on maximum current while the maximum switching power (per channel) is 10 watts. This module supports a minimum switching load of 10 μA, 10 mV, while the maximum RF carry power (per channel) is 10 Watts up to 500 MHz.
The typical operational relay time is 2.4 ms while the maximum time it takes is 4.4 ms. The expected mechanical relay life is 5 × 107 cycles while the maximum electrical relay life is 3 × 105 cycles at 30 V, 0.3 A, DC resistive. Both the input and the output of the 778793-01 PXI RF Multiplexer Switch Module relay of memory addressable trigger lines. With 8 trigger lines for the input and 8 for the output, the 778793-01 PXI RF Multiplexer Switch Module uses a 150 ns PWM trigger signal for controlling the input while a software programmable trigger signal of 1 μs to 62 μs is used for the output.
This module features electromechanical latching relay types made with silver palladium and gold for providing corrosion protection and increasing heat tolerance. This module has 18 MCX jacks and 2 SMB jacks for trigger connections. The PXI power requirement is 3.5 Watss at 5 Volts, and 1 Watts at 3.3 Volts, while the PXI Express power requirement is 4.5 Watts at 12 Volts and 1 Watts at 3.3 Volts.
This module has dimensions of 21.6 × 2.0 × 13.0 cm (8.5 × 0.8 × 5.1 in.) and weighs 330 g (12 oz). It has an operating temperature rating of 0 °C to 50 °C with a storage rating of -20 °C to 70 °C and a humidity rating of 5% to 85%, noncondensing. The module has a pollution degree of 2 and has an altitude rating of 2000 meters.
