National Instruments 783126-01 RF Analog Signal Generator

Part number 783126-01 from National Instruments is the descriptive part number for the version of the PXIe-5654 RF Analog Signal Generator that is equipped with 10 GHz of frequency. The 783126-01 offers exceptional agility with a variety of features, including fast switch. Two of the standout characteristics of this signal generator are it’s excellent phase noise and frequency tuning time. The device offers a range of flexible features, designed to meet the demanding needs of testing scenarios such as RFIC characterization, radar applications, and satellite testing.

The fast switch capabilities of this signal generator are found under the part number 783126-02. For frequencies under 250 MHz, fast switch enables the device to tune to and from any frequency in 100 µs or 150 µs. If a frequency switch surpasses the threshold of 250 MHz in a high-to-low direction, the frequency settling time is lengthened. The typical frequency settling time with fast tuning is 100 µs. Without it, the typical frequency settling time is 1 ms. Whenever the frequency switches with the 783126-02, there is a corresponding amplitude settling time that is linked to changes in the internal hardware settings. The duration of the amplitude settling varies according to whether the device in closed-loop or open-loop mode.

The front panel of the 783126-01 features two LED indicators that provide visual insight as to the status of the device. The ACCESS LED displays the status of the signal generator’s basic hardware- showing an amber color when the module is being accessed and a green color to indicate that it is ready to be programmed. The ACTIVE LED shows a green color when the device is running and a red color is an error had been detected.

Weighing just 1,328 g (46.8 oz), the 783126-01 measures dimensions of 6.1 cm x 13.0 cm x 21.4 cm (2.4 in. x 5.1 in. x 8.4 in.).
