The Aim-TTi Soft Carry Case for PFM1300/3000 provides protection for the Hand-held Frequency Counter when in transit. The PFM1300/3000 has been strongly made and heavily padded.

The PFM3000 offers high sensitivity frequency measurement from 3Hz to more than 3GHz in two overlapping ranges. Period measurement is also provided from 8ns to 330ms.

The PFM3000 uses a continuous reciprocal measurement technique to provide high resolution at all frequencies with rapid update. It offers high sensitivity across the whole frequency range. A low pass filter can be selected to reduce high frequency signal noise at lower frequencies. Despite its compact dimensions, the PFM3000 incorporates a large 8 digit LCD. Annunciators are provided for measurement function, measurement time, overflow, trigger activity, low battery, and measurement units.

Despite its wide frequency range the PFM3000 has a power consumption that enables it to operate for many hours from a PP3 size battery. A push-to-measure capability gives an instantaneous reading followed by an automatic power down after 15 seconds. This provides greatly extended battery life where continuous monitoring of the signal is not required.

Bench-top use The PFM3000 has the performance needed for many bench-top applications, and its built-in tilt stand sets the display at a convenient angle.

The TF930 is a portable, battery-operated, universal counter with a large 0.5 inch 10-digit liquid crystal display (LCD). The frequency range is 0.001Hz to 3GHz and measurement functions include frequency, period, ratio, pulse width and count.The instrument uses a high quality temperature compensated internal frequency reference which has a low aging rate and is stable to within ±1ppm over the full temperature range. Its short warm-up time allows accurate measurements to be made even under portable battery powered conditions.Input A has configurable coupling (AC or DC), input impedance (1MW or 50W), attenuation (1:1 or 5:1), threshold (fully variable) and active edge and can be used for frequencies in the range 0.001Hz to >125MHz.Input B is a nominal 50W input for frequencies in the range 80MHz to 3GHz.An External Reference input is provided and changeover from the internal time base is automatic when an external reference standard is connected.For frequency, period and frequency ratio functions the instrument uses a reciprocal counting technique to provide high resolution at all frequencies. 8 significant digits of answer are produced in a 1 second measurement time, 9 digits in 10s and 10 digits in 100s with a granularity of less than 2 counts in the least significant digit.Indicators show measurement input configuration and function, measurement time and status, external reference connection, low battery and the units of the measurement which may be Hz, kHz, MHz, ns, us, ms or s.The instrument has a USB interface which allows it to be remotely controlled using RS232 protocol via a computers USB port. The remote commands of its predecessor instrument, the TF830, are compatible with the TF930 command set. The instrument can also be powered from a standard USB port.The instrument operates from internal rechargeable NiMH batteries which give typically 24 hours operating life. The universal AC charger supplied will recharge the batteries in less than 4 hours and can be used for continuous AC operation.

The Textronix FCA3000 is a Timer/Counter/Analyser that packs many different functions into one feature-rich instrument. With industry leading frequency and time resolution, the FCA3000 comes with deep internal memory as standard, and a fast data transfer rate of 250k Samples/s to internal memory.

In addition, the multi-parameter display shows auxiliary measurements alongside your main measurement to provide you with the results you need at a glance. With the industry's most comprehensive analysis modes, including measurement statistics, histograms, and trend plots, you have the tools you need to quickly and accurately analyse your signal.

A high-resolution screen is critical for R&D and production testing on today's demanding designs. The device delivers a 12-digit frequency resolution and for time measurements. With the unique display of the FCA3000, you can measure multiple parameters of the same signal from one test connection. To reveal signal quality issues like drift, intermittent transients, and stability, you can view the data as a real-time trend plot or a histogram with the FCA3000 graphical display mode, or you can use measurement statistics to track how signal parameters are changing over time. A single-button Analyse mode gives you fast insight into the behaviour of your device right on the timer/counter's display.
