The Keysight (formerly Agilent) 34401A provides 6½ digits of resolution and performance rivalling multimeters costing many times more. One or two button presses give you a wide array of functions such as DC volts, frequency, dB and dBm. Advanced tests include limit checks that drive a TTL output, min/max/avg readouts and DC voltage ratios.
Keysight Intuilink (Agilent Intuilink) software is supplied free with the 34401A, and allows you to use your captured data with PC applications such as Excel or Word. Programmers can save time by using ActiveX controls with SCPI commands when using Keysight VEE (Aglient VEE), C/C++, VB and LabVIEW.'
