53200 Series RF & universal frequency counter/timers

(Data sheet publication number: 5990-6283EN)

A family of universal and

RF counters to meet your needs

Agilent Technologies 53131A/132A/

181A high-performance counters give

you fast, precise frequency measure-

ments at an affordable price. These

counters feature an intuitive user

interface

and one-button access to

frequently

used functions so you can

make accurate measurements quickly

and easily.

Real-time digital signal processing

technology is used to analyze data

while simultaneously taking new read-

ings, speeding measurement through-

put. The technology, developed for

Agilent’s high-end line of modulation

domain analyzers, allows the counters

to gather more data for each measure-

ment, so you get higher-resolution

measurements in a fraction of the time

it takes other counters.

The 53131A/132A/181A counters offer

built-in statistics and math functions

so you can scale measurements and

simultaneously measure and track

average, min/max and standard devia-

tion. Automated limit testing lets you

set upper and lower limits for any mea-

surement. An analog display mode lets

you see at a glance whether a mea-

surement is within pass/fail limits. The

counters flag out-of-limit conditions

and can generate an output signal to

trigger external devices when a limit

is exceeded. For quick access to fre-

quently used tests, a single keystroke

recalls up to 20 different stored front-

panel set-ups.

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 per second.

The standard RS-232 talk-only interface

provides printer support or data trans-

fer to a computer through a terminal-

emulation program.

Agilent 53131A universal counter

The two-channel 53131A counter offers

10 digits per second of frequency/

period resolution and a bandwidth of

225 MHz. Time interval resolution is

specified at 500 ps. An optional third

channel provides frequency measure-

ments up to 3 GHz, 5 GHz, or 12.4 GHz.

Standard measurements include fre-

quency, period, ratio, time interval,

pulse width, rise/fall time, phase

angle, duty cycle, totalize, and peak

voltage.

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/sec frequency/

period resolution and 150 ps time

interval resolution. In addition, the

53132A offers advanced arming modes

for time interval measurements.

Agilent 53181A RF counter

Optimized for RF applications, the

single-channel 10 digit/s 53181A

measures frequency, period and peak

voltage. A digit-blanking function lets

you easily eliminate unnecessary digits

when you want to read measurements

quickly. For higher-frequency measure-

ments, choose an optional second

channel that provides measurements

up to 1.5 GHz, 3 GHz, 5 GHz, or 12.4 GHz.

A self-guided shallow menu makes this

counter exceptionally easy to use.

Agilent IntuiLink provides easy access

to the counter’s data from your PC

The Agilent 53131A/132A/181A

counters, capture precise frequency

and time measurements. IntuiLink

software allows that data to be put

to work easily. You work in a familiar

environment at all times, using PC

applications such as Microsoft Excel®

or Word® to analyze, interpret, display,

print, and document the data you get

from the counter.

It gives you the flexibility to configure

and run tests from your PC making

data gathering more convenient.

Agilent IntuiLink lets you:

• Configure tests, including measure-

ment type, number of readings,

measurement speed, and more.

• Choose display modes from real-

time strip chart, histogram, readout,

and table mode.

• Scale measurements data.

• Copy captured data to other

programs.

Optional timebases offer

increased stability

Optional timebases are available

for 53131A/132A/181A counters to

increase measurement accuracy. Option

010 provides a high stability oven

timebase with aging of less than

5 x 10-10 per day.

1-year warranty

Measurement Specifications

Auto arming: Measurements are initiated

immediately and acquired as fast as possible,

using a minimum number of signal edges.

Timed arming: The duration of the measurement

is internally timed to a user-specified value

(also known as the “gate time”).

Digits arming: Measurements are performed

to the requested resolution (number of digits)

through automatic selection of the acquisition

time.

External arming: An edge on the external arm

Input enables the start of each measurement.

Auto arming, timed arming modes or another

edge on the external arm input may be used to

complete the measurement.

Time interval delayed arming: For time interval

measurements, the stop trigger condition is

inhibited for a user-specified time following the

start trigger. The 53132A offers advanced time

interval arming capabilities including use of user

specified time or Channel 2 events to delay both

start and stop triggers.

Measurement limits

Limit checking: The measurement value is

checked against user-specified limits at the

end of each measurement.

Display modes: The measurement result may

be displayed as either the traditional numeric

value or graphically as an asterisk moving

between two vertical bars.

Out-of-limits Indications:

• The limits annunciator will light on the front

panel display.

• The instrument will generate an SRQ if

enabled via GPIB.

• The limits hardware signal provided via the

RS-232 connector will go low for the duration

of the out-of-limit condition.

• If the analog display mode is enabled, the

asterisk appears outside the vertical bars,

which define the upper and lower limits.

For measurements using Ch3,

substitute Ch3 for Ch2 in these

equations. To minimize relative

phase measurement error,

connect the higher frequency

signal to channel 1.

Fractional time base error (see graph 3)

Time base error is the maximum fractional frequency variation of the time base due to aging or

fluctuations in ambient temperature or line voltage:

∆f ∆f ∆f

Time base error

= ( —

Aging rate

+ —

Temperature

+ —

Line voltage

)

f f f

Multiply this quantity by the measurement result to yield the absolute error for that measurement.

Averaging measurements will not reduce (fractional) time base error. The counters exhibit negligible

sensitivity to line voltage; consequently the line voltage term may be ignored.

Trigger error

External source and input amplifier noise may advance or delay the trigger points that define the

beginning and end of a measurement. The resulting timing uncertainty is a function of the slew rate

of the signal and the amplitude of spurious noise spikes (relative to the input hysteresis band).

The (rms) trigger error associated with a single trigger point is:

Trigger error =Input signal slew rate at trigger point (in seconds)

(E )

input

2(E )

signal

where

Einput = RMS noise of the input amplifier: 1 mVrms (350 µVrms typical). Note that the internal

measurement algorithms significantly reduce the contribution of this term.

Esignal = RMS noise of the input signal over a 225 MHz bandwidth (100 kHz bandwidth when the

low-pass filter is enabled). Note that the filter may substantially degrade the signal’s slew rate at

the input of the trigger comparator.

For two-trigger-point measurements (e.g. rise time, pulse width), the trigger errors will be referred

to independently as start trigger error and stop trigger error.

Trigger level timing error (see graph 6)

Trigger level timing error results from a deviation of the actual trigger level from the specified level.

The magnitude of this error depends on resolution and accuracy of the trigger level circuit, input

amplifier fidelity, input signal slew rate, and width of the input hysteresis band.

The following equations should be summed together to obtain the overall trigger level timing error.

At the “High” sensitivity input setting, the hysteresis band can be assumed to be the sensitivity of

the counter input (see page 2). Reduction of input sensitivity or use of the attenuator will increase the size of this band.

Input hysteresis error: –

Trigger level setting error: ± ±

Differential channel error

The differential channel error term stated in several systematic uncertainty equations accounts for

channel-to-channel mismatch and internal noise. This error can be substantially reduced by performing

a TI calibration (accessible via the utility menu) in the temperature environment in which future

measurements will be made.

7. Graphs 1, 2, 4 and 5 do not reflect the effects of

trigger error. To place an upper bound on the added

effect of this error term, determine the frequency

error from the appropriate graph and add a trigger

error term as follows:

Trigger error per trigger point

Available statistics

Mean, Minimum, Maximum, Standard Deviation

Number of measurements 2 to 1,000,000.

Statistics may be collected on all measurements

or on only those which are between the limit

bands. When the limits function is used in

conjunction with statistics, N (number of

measurements) refers to the number of in-limit

measurements. In general, measurement

resolution will improve in proportion to N,

up to the numerical processing limits of

the instrument.

Measurements

Statistics may be collected for all measurements

except peak volts and totalize.

Save and recall

Up to 20 complete instrument setups may

be saved and recalled later. These setups

are retained when power is removed from

the counter.
