Frequency counters are depended on in research and development and also in manufacturing for the fastest, most accurate frequency and time interval measurements. The Keysight 53210A (Agilent) Universal Frequency Counter expands on this expectation to provide you with the most information, connectivity and new measurement capabilities, while continuing to build on, already reliable, speed and accuracy.

Features and Specifications of:

●Single-channel, RF frequency counter

●One 350 MHz input channel, plus optional second channel (6 GHz or 15 GHz)

●10 digits/second resolution

●Built-in math analysis and color, graphical display (trend and histogram)

●LXI-C/LAN and USB standard, GPIB optional

●Optional: Lithium Ion Battery

●Input Characteristics:

■Input Event Thresholds:

■Threshold Levels: ±5 V (±50 V) in 2.5 mV (25 mV) steps

■Noise Reject: Selectable On/ Off

■Slope: Selectable Positive or Negative

■Auto-scale: Acquires signal for current measurement channel, selects range (5 V or 50 V), sets auto-level 50%

■Auto-level: Selectable On or Off:

■On: Sets auto-level (% of Vpp) operation

■Occurs once for each INIT or after a timeout

■Measures signal Vpp and sets Trigger level to 50%

■Off: Selectable user set level (Volts)
