Agilent 53220A Universal digital Frequency Counters

Agilent 53220A Universal digital  Frequency Counters

Agilent 53220A Universal Frequency Counter Timer 350 MHz . The 53220A 350 MHz universal frequency counter/timer is a two-channel frequency counter with the ability to make all the frequency and time interval measurements you depend on. An optional microwave channel can be added to measure 6 or 15 GHz.

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 Agilent's decades of time and frequency measurement expertise.

1. AC coupling occurs after 50 O termination.

2. 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.

3. Multiply value(s) by 10 for the 50 V range.

4. Stated specification assumes Noise Reject OFF. Noise Reject ON doubles the sensitivity minimum voltage levels.

5. Assumes sine wave.

6. 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.
