The Racal-Dana 1998 frequency counter offer a combination of superior performance and measurement capability in a compact half-rack package. The 1998 utilize microprocessor control, togather with advanced LSI technology to provide outstanding technical performance with operational simplicity. Frequency, period and ratio measurement modes are incorporated with the capability of external aming, nuling and single shot measurement. In addition, extensive GPIB programmability, ideal for integration into ATE systems, or bettery pack for portability are available.
The 1998 accepts up to 7V r.m.s. with fuse protection to 25W, thus minimizing risk of damage. Optimized control produce and easy-to-use counter. On input A, both fixed attenuation and variable sensitivity give enhanced control when dealing with noisy signals. Trigger offset is also available to accept both sinewave and wide mark-to-space ratio pulses.
A wide range of internal frequency standard is available to provide the counters with the ideal accuracy and stability for any application. Packaged crystal, temperature compensated crystal oscillators (TCXO) and a range of proportionaly controlled ovened oscillators are available for bench, system, bettery-portable or precision measurement applications. A standby mode ensure that power is supplied continuously to the ferquency standard to maintain maximum stability, if required.
