Features


Wide dynamic range of sourcing

The 6146/6156 adopts source or sink-enabled bipolar output within a range of ±32 V and ± 220 mA. Zero-crossing continuous variable output from negative to positive and vice versa is available. 

 

6146/6156 Wide Dynamic Range of Sourcing

High-speed response and low noise voltage/current sourcing

6146/6156 High-Speed Response and Low Noise Voltage/ Current Sourcing

The response time in voltage or current sourcing of the 6146/6156 is greatly improved compared to the former models, and the settling time to reach the final value ±0.1 % of 10 ms or less is achieved. Consequently, the characteristic evaluation time for components or modules or the takt time for automatic test can be greatly reduced.

Also, it features low output noise of 100 μVp-p (30 V range, DC to 100 Hz band), enhancing the measurement reliability in characteristic evaluation of semiconductors or sensors. 

Suspend function suitable for automatic tests

When DUTs such as electronic components or modules are replaced on automatic test equipment, the output status needs to be “Standby” that opens the output relay so as not to apply unnecessary voltage to the DUTs. Every switching between "Operate" and "Standby" turns ON or OFF the output relay, giving a great impact on the relay lifetime.

The 6146/6156 has a suspend function that keeps the output status in "high impedance (HiZ: output relay ON, high resistance)" or "low impedance (LoZ: output relay ON, low resistance)" without switching the relay. The output OFF status can be selected from these two statuses and “Standby (output relay OFF).”

Using this function can extend the relay lifetime and improve the system throughout. In addition, it can prevent transient current from being generated when connecting voltage sourcing devices such as batteries.

6146/6156 Suspend Function Suitable for Automatic Tests

Multiple-unit operation and synchronous operation with DMM

In an electronic device or module test, voltage sometimes needs to be applied from more than one source. In this case, voltage to be applied to DUTs needs to vary in a synchronous timing.
More than one 6146/6156 units can be synchronized by connecting the Operate and Standby timing signals and variable voltage timing signals from the master to its slaves.

For voltage measurement using DMM, the 6146/6156 builds up an automatic measuring system with the DMM with the minimum waiting time as voltage application timing and measurement timing can be synchronized.

6146/6156 Multiple-Unit Operation and Synchronous Operation with DMM

The 6146/6156 has a signal line for synchronous control so that multiple units can output signals in synchronization. The following shows an example of how three 6146/6156 units synchronize sweep operation using control signals. “SYNC OUT”and“OPERATE IN OUT”signals from the master are connected to“TRIGGER IN”and“OPERATE IN OUT”signals of its slaves.

HI/LO limiters separate setting

The limiter function is highly important for voltage or current sourcing to protect connected devices.
The current limiter works for voltage source to restrict output current and the voltage limiter works for current source to restrict compliance voltage. The 6146/6156 has two setting levels for both voltage and current limiters which can be set separately.

User Friendly Operation Panel

6146/6156 User Friendly Operation Panel

Voltage or current values to be generated can be entered directly using the keyswitches on the front panels, and can be varied (increased or decreased) continuously by specifying an arbitrary digit using the rotary knob or the UP and DOWN keys. Thus, the operability is greatly improved, so that measurement such as a device input and output characteristic test can be performed by simple key operations.

Thermal electromotive force output function (6156 only)

The 6156 is capable of generating thermal electromotive force of thermocouples in accordance with JIS standards. Selecting the type of thermocouple and temperature to be generated will output voltage corresponding to the setting temperature.
The type of thermocouple is selectable from type T, J, E, K, S, R, B and N. The reference junction compensation is at 0 ℃ or arbitrary temperature (user selectable).
This function enables temperature calibration of thermometers and other measuring instruments.

The 6156 thermal electromotive force output function can linearize the temperature and the thermal electromotive force of each thermocouple. Thus, thermometers can be calibrated easily just by setting the temperature to be calibrated on the 6156.
