National Instruments 787251-01 PXI Vector Network Analyzer

Part number 787251-01 from National Instruments is the descriptive part number for the CMT PXIe-S5090 PXI Vector Network Analyzer. Designed in collaboration with Copper Mountain Technologies, this vector network analyzer is designed to accurately measure how signals are transmitted and reflected at various frequencies. Featuring 2 test port connectors with 3.5 mm (female) connectors, the 787251-01 is easily integrated into test systems of all sizes. 512 MB of RAM offers plenty of space for projects, and the power supply requires a mere 1.5 A for voltages from 3.3 V to 12 V. This versatile analyzer boasts a frequency range of 300 kHz to 9 GHz with a resolution of 1 Hz, making it an excellent choice for a wide range of applications.

The 787251-01 is equipped with a both a Trigger Input and a Trigger Output port. These ports are labeled Ext. Trig In and Ext. Trig Out, respectively. Both of these ports feature SMB male connectors, and their input levels differ depending on voltage. The low threshold voltage for the Trigger Input of the device is 1.1 V, while the high threshold is 2.6 V. For the Trigger Output, the low output level voltage ranges between 0.0 to 0.6 V, while the high level ranges from 3.0 to 3.8 V. Both the input and the output of the 787251-01 feature either positive or negative polarity.

In terms of physical environment specifications, the 787251-01 operates best when used in temperatures ranging from 5 °C to 40 °C. When it is not being used, it can be stored safely in temperatures spanning from -50 °C to 70 °C. The device measures 221 mm x 129 mm x 20 mm abd weighs 0.6 kg (21.2 oz).
