Description of the 225 MHz Universal
Counter
The HP 53131A and HP 53132A are universal counters capable of
measuring frequencies to 225 MHz on Channels 1 and 2. With an optional
Channel 3 Option 030, Option 050, or Option 124, this capability is
extended to 3.0, 5.0, or 12.4 GHz, respectively.
For the HP 53131A, frequency and time interval resolutions are 10 digits
in one second and 500 picoseconds, respectively. The HP 53131A provides
users with a HP-IB measuring speed of up to 200 measurements
per second, and is suitable for bench-top operation and lower-volume ATE
operation. The frequency and time interval resolutions for the HP 53132A
are up to 12 digits in one second and 150 picoseconds, respectively.
The HP 53132A provides users with exceptional resolution, and is ideal
for ATE systems operation.
The HP 53131A/132A basic measurement functions include Frequency,
Period, Pulse Width, Duty Cycle, Rise/Fall Time, Time Interval,
Frequency Ratio, Totalize, Phase, and Peak Voltage.
The HP 53131A/132A Counter has four arming modes: auto, external,
digits and time. However, the HP 53132A with serial number prefix 3646
and above has expanded arming capabilities for Time Interval
