FREQUENCY COUNTER RESOLVES TO MICROHERTZ
03 June 2005 - Thurlby Thandar Instruments Ltd
| The newly revised TF830 from TTi is an 8-digit 1.3 GHz frequency counter which uses an all-new 2U height bench-top case and can measure low frequencies to a resolution of 1 micro Hz. The TF830 uses the reciprocal frequency counting technique to achieve high resolution at all frequencies. |
The newly revised TF830 from TTi is an 8-digit 1.3 GHz frequency counter which uses an all-new 2U height bench-top case and can measure low frequencies to a resolution of 1 micro Hz. The TF830 uses the reciprocal frequency counting technique to achieve high resolution at all frequencies. Reciprocal counting involves synchronised multiple period measurements followed by computation of the reciprocal value. This results in high-resolution measurements regardless of the signal frequency and eliminates the ±1 input cycle errors of a conventional frequency counter. As well as measuring low frequencies to a resolution of 1 micro Hz, the system yields at least seven digits of resolution per second of measurement time. In addition to frequency measurement, the TF830 offers period measurement, frequency ratio, pulse-width measurement and event counting. Pulse-width measurements can be made from rising to falling edge or vice versa. A version of the TF830 with an RS232 interface is also available in which all functions can be remotely controlled, and measurements can be read back to the controller. This makes it suitable for use in a wide variety of automatic measurement systems. The TF830 uses an LCD display, and its low power consumption allows it to be operated from internal batteries as well as from its internal AC power supply.
The TF830 costs £203 (plus VAT) in the UK.

About: Thurlby Thandar Instruments Ltd
TTi (Thurlby Thandar Instruments) is a major European manufacturer of electronic test and measurement instruments.These products are sold throughout the world via distributors and agents. Within the UK, TTi sells both its own manufactured products and a wide range of instruments from other European, American and Japanese manufacturers. TTi is located in Huntingdon near Cambridge in England. The origins of TTi date from the late 1970s when two separate companies, Thurlby Electronics Ltd. and Thandar Electronics Ltd. were both designing and manufacturing electronic test equipment within close proximity at St. Ives in Cambridgeshire. Through the 1980s, Thurlby specialised in bench power supplies, high resolution multimeters and digital storage units; whilst Thandar specialised in function generators, frequency counters and logic analysers. In 1989 the two companies were merged into a new organisation - Thurlby Thandar Instruments Ltd. - and located to larger premises in nearby Huntingdon. Through the 1990s the existing product ranges were expanded and new product areas developed including arbitrary waveform generators, EMC measurement equipment and component bridges.
In 1999, TTi acquired the product ranges of Black Star Instruments and incorporated them into the TTi range. In addition to selling the TTi range of products throughout the world, the company has also expanded its UK sales operation to represent other major producers of test equipment. Today TTi is one of the foremost producers of general purpose electronic test instruments and laboratory power supplies in Europe, selling products in over fifty countries. It is also one of the largest distributors of test and measurement equipment in the UK representing many leading American, European and Japanese producers within the United Kingdom market. |
