HP5315A   1 GHz

Reciprocal Counter

This is a great portable lightweight counter suitable for both bench and high accuracy field measurements. This exceptional value is being overlooked with the glut of HP 53132A and 53131A's hitting the market. Yet these counters perform as well in many applications, are more user friendly, and sell for substantially less. This instrument includes the C channel option (Opt. 003) extending measures to 1.0 GHz for both CW and pulsed RF signals as narrow as 60 ms. This makes it particularly useful for navigation and communication equipment testing. This counter also has outstanding low frequency performance, delivering its full 8-digits/second resolution over the range from 1 Hz to 100 MHz (A and B channels). Reliability is excellent due to the low chip count. This unit also has continuously adjustable gate time, which allows for easy trade-offs between measurement time and resolution.   

  • Frequency range from 0.1 Hz to 1 GHz.

  • 10 mV sensitivity to 10 MHz, 25 mV to 100 MHz.

  • Period range from 10 ns to 1,000,000 s.

  • Ratio, totalize, and A gated by B measurements.

  • Eight digit display with Nine digit overflow. 

This unit is in mint mechanical and electrical condition.  It is beautifully constructed with gold traces and high-grade circuit boards. Many of the standard units have been listed on eBay, however, units with the C channel option are rarely available anywhere. Here is an opportunity to own this versatile counter in nearly new condition.
