Data Sheet
Imagine Your Counter Doing More!
Introduction
Frequency counters are depended on in R&D and in manufacturing for the fastest, most accurate frequency and time
interval measurements. The 53200 Series of RF and universal frequency counter/timers expands on this expectation to
provide you with the most information, connectivity and new measurement capabilities, while building on the speed and
accuracy you’ve depended on with Keysight Technologies, Inc. time and frequency measurement expertise.
Three available models offer resolution capabilities up to 12 digits/sec frequency resolution on a one second gate. Single-
shot time interval measurements can be resolved down to 20 psec. All models offer new built-in analysis and graphing
capabilities to maximize the insight and information you receive.

AC coupling occurs after 50 Ω termination.
When ordered with optional rear terminals, the standard/baseband channel inputs are active on both the front and rear of the universal
counter though the specifications provided only apply to the rear terminals. Performance for the front terminals with rear terminals installed
is not specified.
Multiply value(s) by 10 for the 50 V range.
Stated specification assumes Noise Reject OFF. Noise Reject ON doubles the sensitivity minimum voltage levels.
Assumes sine wave.
CW only. Assumes AM Rate > 10/gate. For Option 106, spec applies for input powers > -20 dBm; use a tolerance of 15% modulation depth
for frequencies less than 900 MHz. For Option 115, spec applies for input powers > -10 dBm.
