Precision DC voltage/current source best used as calibrator or secondary battery simulator

The 6156 is a high-precision DC voltage/current source suitable for semiconductor or electronic components characteristics evaluation and for calibration of meters or measuring instruments. Its convenient ability to synchronize with multiple units or other instruments makes it perfect for system use in electronic component test systems.

Features & benefits

Fast response and low noise

Supply quality without compromises

The voltage and current sourcing response times of the 6156 have greatly improved compared to the former models – with a settling time of 10 ms or less to reach the final value ±0.1 %. This makes it possbile to greatly reduce the characteristic evaluation time for components or modules or the takt time for automatic testing. The 6156 also features a low output noise of 100 μV (peak-to-peak) (30 V range, DC to 100 Hz band), enhancing the measurement reliability during characteristic evaluation of semiconductors and sensors.

Suspend function

Suspend function with HiZ/LoZ  output impedance selection

When DUTs such as electronic components and modules are replaced on automatic test equipment, the output status needs to be “Standby” so that the output relay opens to prevent unnecessary voltage to the DUTs. Every switch between “Operate” and “Standby” turns the output relay on or off, which greatly impacts relay lifetime. The 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. Using this function can extend the relay lifetime and improve  system throughout. It can also prevent transient current from being generated when connecting voltage sourcing devices such as batteries.

Different output status modes

Synchronous and multiple-unit operation

Convenient trigger and synchronization capabilities

When testing an electronic device or module, voltage sometimes needs to be applied from more than one source. In this case, the voltage to be applied to DUTs needs to synchronously vary. Multiple 6146 units can be synchronized by connecting the operate and standby timing signals and the variable voltage timing signals from the master to its slaves. For voltage measurements using the DMM, the 6146 sets up an automatic measuring system with the DMM with the minimum waiting time since the voltage application timing and measurement timing can be synchronized.


Picture right: 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.

High DUT protection

Separate HI/LO limiter setting

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

Balanced or separate limiter setting modes

User -friendly operating panel

Intuitive operation by direct entry input and/or rotary knob

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

Thermal electromotive force output function

Optimal for temperature calibration of thermometers

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 JIS standard is JISC1602-1995 or JISC1602-1981. This function enables temperature calibration of thermometers and other measuring instruments.

Temperature calibration with different thermocouples

Calibration source

Calibration of meters and measuring instruments

Meters and measuring instruments used in plants or instrumentation systems need to be periodically calibrated.
The 6146/6156 are suitable for calibration of these meters or instruments with their high source accuracy. The calibration time can be reduced by storing voltages or currents of points to be calibrated in the memory of the 6146/6156 and reading them out by turns.

Calibration source for meters

Sensor characterizing

For characterizing strain sensors (strain gauges)

A strain gauge used in a strain or pressure sensor utilizes subtle variations in resistance.
In a strain gauge test, resistance with a known load applied is measured using a Wheatstone bridge circuit.
The highly stable 6146/6156 units are ideal as a voltage source for the Wheatstone bridge circuit.
The output voltage is measured  using a digital multimeter such as the 7461A.

Battery control

For evaluating secondary battery control circuits

Since secondary batteries such as a lithium ion battery have high-energy density, the control circuit plays an important role in monitoring the charge/discharge characteristics. To test the operation of this control circuit, the 6146/6156 can be used as a battery simulator. The control circuit is tested correctly by changing the voltage of the battery simulator for each test item. The 6146/6156 units realize such precise characteristic measurements.
