The 8040 is a full-featured multi-function counter in a compact, bench/portable design. Capable of frequency measurements from near DC to over 3GHz, the 8040 is suited for virtually every application. Outfitted with the optional antenna, its compact size and ultra-high sensitivity make it perfect for "off-the-air" measurements and Frequency Finding using the Digital Filtering and Digital Auto Capture® functions.

The 8040 brings all of the same advanced features found in the 3000A HandiCounter® to a bench/portable configuration. It shares the same specifications for sensitivity, gate times, display resolution, and operating modes as the 3000A. For bench use however, the 8040 adds a complete set of input signal conditioning and trigger level controls for both high impedance input amplifiers. This gives the operator more flexibility in making frequency, period, ratio and time interval measurements on a wider variety of signals. In addition, the 8040 has an RS-232C serial data interface. It can be directly connected to the serial port of a PC and used with the OptoLog data logging software.

The 8040 comes standard with a low power .05 ppm 0-50^oC ovenized oscillator (OCXO). The OCXO is manufactured by KVG for the military and is extremely rugged as well as low in power consumption. The 8040 also comes standard with an internal NiCad battery, for portable use. The LCD display has an electroluminicent (EL) backlight standard.
