Key facts

  • 4 channels with 0 to ±10 V, 0 to ±500 mA, sink-enabled output
  • Minimum resolution 10 µV/10 pA (measurement)
  • DC, pulse, sweep and pulse sweep operation; min. 50 µs pulse width
  • Synchronous operation of channels and multiple units
  • 6541 benchtop unit with color LCD monitor

4-channel compact source monitor capable of synchronous measurements among channels

The low-noise 6540/6541 units integrate multiple channels. They can be used as a power supply for devices and simultaneously as a load, allowing pulse generation of the minimum pulse width of 50 µs, sweep operation and synchronous operation among multiple channels or units. The source and measurement range is 0 to ±10 V for voltage and 0 to ±500 mA for current. They both have a USB interface.

Features & benefits

Synchronous source and measurement

4-channel synchronous operation

The 6540/6541 can synchronize measurements in the DC source mode, and sources and measurements in the pulse source and sweep source modes. Even different waveforms can be generated and measured.
Arbitrary master channel and slave channels are selectable. Up to 3 units can be synchronized, so that up to 12 channels can be operated in sync (3 x 4 channels = 12 channels).

Synchronized operation in different operating modes

Suspend function

Suspend function with HiZ and LoZ output impedance selection

The 6540/6541 can select from three output OFF statuses; STBY (output relay OFF), HiZ (output relay ON and high resistance) and LoZ (output relay ON and low resistance). This means unnecessary relay ON/OFF operations can be eliminated, which can increase product reliability.
In addition, the setting of a suspend voltage (voltage in HiZ and LoZ status) can prevent unwanted leakage currents when connected to voltage sourcing devices such as batteries.

Different output status settings

Application-adapted current mesaurements

Peak/average current determination using well adapted, arbitrary setting integration time

A precise average current measurement has to measure all current passing during a specific DUT operating mode.
The 6540/6541 are capable of accurate average current measurements by measuring the peak current and using the variable integration function (arbitrary setting from 100 µs to 740 ms). This makes it easy to measure the average current consumption of mobile devices.  The peak hold measurement function detects and measures maximum values up to 20 kHz pulses.

Peak and average current measurements

Variable setting integration times for optimal adaptation to DUT's operating modes

Separate HI/LO limiter setting

The limiter function is important for voltage or current sourcing to protect the 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 6540/6541 have two setting levels that can be set separately for both voltage and current limiters. The separate setting capability can prevent overdischarge conditions at batteries or reverse voltage conditions at laser diodes and capacitors.

Non-symmetric limiter setting capability

Conventional (symmetric) limiter settings (dotted line for LOVL) can cause critical reverse polarity conditions at DUTs, e.g. at charging devices.

Internal source and measurement buffer

10 000 cell buffer for source and measurement per channel

All four channels are equipped with an internal 10 000 sample memory and 10 000 random sweep memory, allowing fast data aquisition or fast waveform generation without the need for remote control interaction. They can be triggered and synchronized by external signals or commands.

Sweep and measurement memory

Output response adaptation

Low-noise source combined with fast response time

The 6540/6541 series is based on a linear operation concept. This enables not only fast response times on load changes, but also excellent low noise output supply with predictable regulation characteristics. Depending on application needs, the user can select between low or fast response behavior. Its low  range-switching noise allows high-resolution sweeps crossing multiple ranges.

6541 with 4.3 inch color display

Convenient, intuitive operation with different levels of information

The  6541 offers view settings tailored to particular needs: 4-channel overview view or 1-channel detailed setting view. Even the time-wise behavior of each channel can be easily visualized on the display. In addition, an extensive, self-explanatory menu concept provides access to parameter settings. Different colors indicate the channel assignments.
