Yokogawa Universal Counter - TC110/TC120 - The TC110 and TC120 are multifunctional Universal Counter equipped with a GP-IB as standard. These models of Universal Counter are fully GP-IB programmable and allow you to control all your panel setting 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 of this Universal Counter include the digit-masking, scaling, D/A output and handler interface functions.
This Universal Counter has the following features:
Fast sampling
The TC100 Series Universal Counter have an internal memory which allows you to sample and store up to 1024 pieces of data using GP-IB commands. The TC100 Series Universal Counter can achieve a fast sampling rate since the display is not updated when storing measured data into the memory. The stored data can be transferred over GP-IB bus with a "time stamp" so you can see how your data vary with each measurement.
Display of Trigger-level Setpoint
When you are setting the trigger level manually, you can change its setpoint while still continuing measurements. In addition, you can confirm the trigger level digitally on the display. Setting is easy. Use the SETTING key to set the trigger level in 20-mV increments (when ATT = x1).
Digit-masking Function
You can mask the least significant digits as necessary. Masking them allows the measured value to appear only to the degree of accuracy you require (only in the number of digits you require). Use this function when the input signal is unstable or the insignificant digits fluctuate plus or minus one digit in counting a number, due to error. This function is extremely useful when using the Universal Counter as a monitor in the field or on a production line.
Scaling function
The TC100 Series Universal Counter computes the algebraic formula (aX + b) for every measured value X, except for those of peak voltage measurements, where a is the scale factor (scale value), and b is the offset; the constants a and b can be set at the user's discretion. The resulting computation appears on the LED display. One or two different settings of the formula can be saved in the internal memory and retained even after the power is turned off. This function is especially useful when converting to other physical quantities or when measuring a deviation from the reference value.
Gate signal input on Channel B
You can use the input signal on Channel B as an external gate signal for frequency and totalization measurements. In this way, you can set an arbitrary timing to start measurement or you can change the resolution.
Hold-off function
The hold-off function allows you to set a length of time in which signals carrying chatter from relays or systematic noise will be disregarded. The Universal Counter then ignores the input signal for that duration, making your measurements free from noise.
