Description of the 225 MHz Counters
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, this frequency is extended to 3.0 GHz (Option 030); 5.0 GHz
(Option 050) or 12.4 GHz (Option 124).”
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 an HP-IB measuring speed of 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 53181A is a frequency counter capable of measuring frequencies
to 225 MHz on Channel 1. Depending on which optional Channel 2 the
counter contains, this capability is extended to 1.5 GHz (Option 015) or
3.0 GHz (Option 030). The HP 53181A has a frequency resolution of
10 digits in one second.
The HP 53181A provides users with an HP-IB measuring speed of
200 measurements per second, and is suitable for bench-top and ATE
operation.
The HP 53181A basic measurement functions include Frequency, Period,
Peak Voltage, and Frequency Ratio (if Channel 2 is installed).
The HP 53131A/132A/181A include additional measurement functions
and features that are designed specifically for manufacturing and service
applications:
