Description

Features:

• Frequency range of 0.1 Hz to 1.3 GHz
• Resolution of 7 digits
• Measuring times of 0.2/1/10 seconds
• Single, trigger levels of auto-manual-GPIB

The Phillips PM6666 is an economical, easy-to-use counter that meets the demands for high-precision measurements, reliability and durability. The units use reciprocal frequency counting, which yields high resolution measuring results under all conditions, even on low frequency measurements. The high performance counter front ends, providing variable sensitivity and noise immunity increase measuring accuracy.  The counters have high input protection, allowing it to withstand inputs of 12V RMS on the optional 50 ohm RF input and 350V (DC+ac peak) on the 1 Mohm LF input.
