The TC110 and TC120 are  multifunctional universal counters equipped with a GP-IB as standard. These models are fully GP-IB programmable and allow you to control all your panel settings via the GP-IB so you can use these counters in an automated measurement system. With the internal memory that stores up to 1024 data items, you can sample and output data at high speeds with the GP-IB commands. You can also measure a variety of waveform parameters, such as the duty factor and peak voltages, as well as time parameters including frequencies, time intervals and totalizations, all with one counter. Other features include the digit-masking, scaling, D/A output and handler interface functions.
