Cal lab performance in the field
With 10 digits per second resolution, plus overflow (11th and 12th digits), it delivers high accuracy measurements instantly. The standard timebase offers a stability of better than 5E-7 per month, and better than 5E-11 per month with the PM 6685R Rubidium Counter.
Built in capabilities simplify tricky measurements
The PM 6685's built-in intelligence eliminates a lot of button pushing. Just plug it in, and it automatically selects optimum trigger level and input sensitivity for excellent noise immunity.
The analog bar graph displays signal strength and input sensitivity to assist instrument setup and RF tuning applications.
