Agilent 53131A Universal Counter
The two-channel 53131A counter
offers a bandwidth of 225 MHz with
a resolution of 10 digits per second
when measuring frequency or period.
Time interval measurements may
also be made with a resolution of
500 ps. An optional third channel
can be added to any counter to
provide frequency measurements
up to 3 GHz, 5 GHz, or 12.4 GHz.
Agilent 53132A Universal Counter
For applications requiring higher
resolution, the 53132A offers the
same features and functions as the
53131A, with up to 12 digits per
second frequency resolution and
150 ps time interval resolution.
If more accuracy is required, a
choice of optional timebases may
be added to any of the counters.
In addition, the 53132A offers
advanced arming modes for time
interval measurements.
Agilent 53181A RF Counter
Optimized for RF applications, the
single-channel 10 digits per second.
53181A measures frequency, period
and peak voltage. A digit-blanking
function easily eliminates unneces-
sary digits when you want to read
measurements quickly. For higher
frequency measurements, choose
an optional second channel. A self-
guided menu makes this counter
exceptionally easy to use.
Connectivity
For computer-controlled systems
applications, each counter includes
a standard GPIB interface with full
SCPI-compatible programmability
and a data transfer rate of up to
200 fully formatted measurements
