Key Features

All features of the 3000 Plus...

  • Variable resistance to 1 GOhm
  • Variable capacitance to 100 mF
  • Extended AC Voltage frequency to 1 MHz
  • Extended AC Current frequency to 30 kHz
  • USB & GPIB (IEEE-488) interfaces standard
  • Remote command emulation mode
  • 7″ full color touch screen
  • Embedded calibration system


The 4000 Series is aimed at laboratories, manufacturers, and design facilities requiring a wide range of outputs with accuracies up to 8 ppm.

The 4000 Series builds on the trusted reliability of the 3000A Series, offering an updated user interface accessed through a large, 7″ touch screen to enable advanced functionality, including a built-in procedure mode and connection prompts, to minimize errors. USB printer capability supports production line automated test reporting without need for a PC and software



The 4000 Series is protected by Transmille’s I-GUARD protection circuitry protecting the calibrator against accidental damage through wrong connections up to ± 1000V RMS.

All Transmille calibrators have been protected by I-GUARD since 2006



Fitted with low thermal beryllium copper terminals, the 4000 Series enables connection with 4mm banana jacks, spades and bare wire without the need for additional adapters.

LED illumination identifies which terminals should be connected to depending on output settings of the calibrator


Expanding the outputs offered by the 3000A Series, the 4000 Series provides an advanced oscilloscope calibration option with bandwidth calibration of up to 6 GHz with variable level. This expands the calibration workload to include spectrum analyzers and high bandwidth oscilloscopes.

Procedures can be loaded into the 4000 Series via USB memory stick, with results stored for integration back into ProCal software.

The 4000 Series also provides USB printer connectivity standard, supporting a wide range of PCL-compliant printers.



To maintain confidence in your equipment, simply connect an 8000 Series digital multimeter to the rear of the unit and enter ‘self-calibration mode’. The 4000 series will then proceed to measure its outputs automatically and generate a test report which can be exported to a USB memory stick for analysis on a computer, and print a test report via a USB printer for maintaining records.



As with all Transmille products, compatibility with ProCal calibration software is guaranteed. Existing procedures will not need to be re-written, due to Transmille’s unique implementation of flexible standards support where procedures are written around the UUT, not the standard.

Internal Options (Choose At Time Of Order)

PRT/RTD Temperature Simulation (Option PRT, Included in -SYS Models)

The PRT option simplifies calibration of high-accuracy resistance thermometers. Reliable readings are guaranteed regardless of measurement technique, because the calibrator uses passive precision resistors.When the PRT option is calibrated, the precise temperature values on the ITS-90 scale for PT-385 resistors are stored in the memory.  The values can be recalled and displayed every time a specific resistor is chosen, to allow accurate calibration.

When combined with the SIMRC option, an additional 2-Wire variable output is available, which enables simulation of any value.

Simulated Resistance & Capacitance (Option SIMRC, Included in -SYS Models)

This option allows for resistance calibration between cardinal points. It has a continuous resistance range between 0 Ohms and 1 GOhms, with variable capacitance from 0.95uF to 100mF.
