02 | Keysight | 53131A/132A/181A Counters - Data Sheet Overview – 225 MHz bandwidth (optional 1.5, 3, 5, or 12.4 GHz) – 10- or 12-digit resolution with 1 s gate time – GPIB interface and IntuiLink connectivity software standard – Data transfer rate of up to 200 fully formatted measurements/second A family of universal and RF counters to meet your needs The Keysight Technologies, Inc. 53131A/132A/181A high-performance counters give you fast, precise frequency measurements 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 readings, speeding measurement throughput. The technology, developed for Keysight’s high-end line of modulation domain analyzers, allows the counters to gather more data for each measurement, 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 deviation. Automated limit testing lets you set upper and lower limits for any measurement. An analog display mode lets you see at a glance whether a measurement 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 frequently 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 transfer to a computer through a terminal-emulation program. Keysight 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 measurements up to 3, 5, or 12.4 GHz. Standard measurements include frequency, period, ratio, time interval, pulse width, rise/fall time, phase angle, duty cycle, totalize, and peak voltage. Keysight 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. Keysight 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 measurements, choose an optional second channel that provides measurements up to 1.5, 3, 5, or 12.4 GHz. A self-guided shallow menu makes this counter exceptionally easy to use.

11 | Keysight | 53131A/132A/181A Counters - Data Sheet 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.

12 | Keysight | 53131A/132A/181A Counters - Data Sheet 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: 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 4). Reduction of input sensitivity or use of the attenuator will increase the size of this band. Input hysteresis error: 0.5 x hysteresis band Input signal slew rate at start trigger point 0.5 x hysteresis band Input signal slew rate at stop trigger point Trigger level setting error: 15 mV ± (1% x start trigger level setting) Input signal slew rate at start trigger point 15 mV ± (1% x stop trigger level setting) Input signal slew rate at stop trigger point
