Convenience, Portability and Outstanding Performance

The Agilent/Keysight Technologies 53151A 26.5 GHz, 2-Channel CW Microwave Frequency Counter/Power Supply, 1 s/1 Hz, Refurbished offers an uncluttered, feature-laden front panel; its design presents no-compromise performance and quality in a surprisingly small, light, battery operated product.

The Convenience Of Single Microwave Inputs

The 53151A has an advanced sampler that integrates a separate zero bias Schottky diode for the accurate measurement of input power. This allows measurement of both frequency and power with a single connection. No compromise in frequency coverage is required for this capability. The ultrawideband microwave input covers the entire RF and microwave spectrum, from intermediate frequencies IFs) of 50 MHz to millimeter waves. The power measurement accuracy and repeatability of this counter rivals power meters with diode sensors. Since frequency and power of the input signal are measured simultaneously, adjustment for the diode's frequency response is done automatically. And like the latest in diode sensors, compensation is also made for deviation from square law.

Field Tough But Ready For Benchtop Or ATE Applications

The 53151A is as comfortable in the field as in the laboratory. The rugged case with an integrated tilting handle can tolerate the vibration and shock expected in field use. The backlit LCD display ensures visibility in all enviroments, from dark to full sunlight, at distances exceeding 15 feet.

If AC power is unavailable, the internal, replaceable camcorder batteries provide at least 2.5 hours of continuous operation. The unit can also be powered from an external 11-18 VDC source.

For benchtop and ATE applications, the 53151A delivers full functionality and high measurement speed. The fully programmable RS-232 interface and high speed GPIB interface are standard features.

Uncompromising Performance

The 53151A offers exceptional sensitivity by utilizing a single board design with low phase noise PLL circuitry. Despite their simple appearance, this counter retains all of the powerful functions one expects in precision instrumentation: measurement averaging, arbitrary as well as nulling offsets for both frequency and power, display of power in either dBm or Watts.

Additional capabilities include full control of resolution, sampling rate, and GPIB address, plus extensive self-diagnostics, fast acquisition times and full programmability. Performance surpasses the industry standard Keysight 5350 Series, in virtually every aspect, in a package less than half the weight and size.
