Hand-Held Counter Offers High Resolution
The low cost of under 100 GBP puts the PFM1300 hand-held frequency counter into the same price category as hand-held multimeters.
The PFM1300 from TTi (Thurlby Thandar Instruments) is a UK-built hand-held frequency counter which can measure signals from 5 Hz to 1300 MHz Its low cost of under 100 GBP puts it into the same price category as hand-held multimeters

High-accuracy LCR meters
The SRS SR715/720 family of LCR meters, now available in the UK from TTi (Thurlby Thandar Instruments), quickly and accurately measures passive components with as little as 0.05% error.
Despite its compact size and low cost, the PFM1300 incorporates many advanced features.
In particular, it uses the 'reciprocal counting' technique to achieve high measurement resolution at all frequencies.
Reciprocal counting uses multiple period measurements followed by computation of the reciprocal value.
This results in a high-resolution measurement regardless of the signal frequency.
The system yields at least 7 digits of resolution per second of measurement time, and can resolve low frequencies to 0.001 mHz (0.000001 Hz).
The frequency range is from 5 Hz up to 1300 MHz with excellent sensitivity throughout (typically 15 mV).
A low-pass filter can be selected when required.
Signals can also be displayed in terms of period as an alternative to frequency from 5 Hz up to 25 MHz.
A 'hold' key allows readings to be frozen on the display whenever required.
The counter is housed in a robust ABS case measuring 81 x 173 x 30 mm (3 x 7 x 1.2 in) and weighing less than 200 g (7 oz).
A large LCD display of very high contrast with 11.5 mm high characters is incorporated.
The display incorporates 15 annunciators covering measurement function, measurement time, units, overflow, trigger activity and low battery.
Low power consumption circuitry ensures long battery life.
A 'push to measure' facility is also incorporated which provides an immediate reading on the press of a key followed by an automatic power-down after 15 seconds, thus ensuring maximum battery life when continuous signal monitoring is not required.
The PFM1300 costs 99.00 GBP (plus VAT).
