The DS Instruments DAT64L Digital Programmable Attenuator is a compact stand-alone and USB-controlled RF Step Attenuator with 0.5dB steps and a range of 0 to 63dB. This premium version features a bright OLED display and front user control buttons. Input frequency ranges from 1MHz to 6GHz. No host PC is required to use this device. Automated scripted control is extremely easy requiring no extra drivers, just a simple virtual COM port connection and SCPI based text commands.
For our 0.25dB step size version with optional Ethernet, see the new DAT64F.
Note that we offer this device for a lower price without the display and buttons for automated USB controlled applications.
