The BM6010A is a Standards Laboratory grade instrument used to measure accurately high-frequency or microwave power in terms of substituted DC power. The BM6010A is an improved replacement for well known Technology Type II bridge power measurement system.
The BM 6010A is a self-calibrating measuring bridge for measuring RF power using a bolometer.
Not only highly sensitive - but also particularly precise.
The BM6010A design goal was to replace or supersede the Tech II bridge in every aspect. As the TechII bridge was commonly used as a standards lab calibration instrument, the requirements in terms of precision, stability and quality are very high. The BM6010A meets all those requirements and is already used at National Metrology Institutes to aid primary reference calibration.
In comparison to the venerable Tech Type II bridge, the BM6010A profits from modern electronics components and a carefully revised overall design. In addition, the instrument is now microprocessor controlled. The modern, intuitive touch screen operation as well as a complete remote control capability using SCPI compatible commands is extremely user friendly. The BM6010A can therefore be used in a complete remote controlled environment, operating at the highest standards.
Many improvements have been made during the development of the BM6010A. The complete bridge circuit is now much more stable, resulting in a usually stable operation without any oscillation or the need of external capacitors.
The reference voltage source operates on a completely new level. Unprecedented in linearity and stability, the need for an external reference voltage source is eliminated. With a linearity error of 1.5 µV/V, the reference voltage source even outperforms many dedicated reference voltage sources. In combination with the remote control capability, the BM6010A is the perfect fit for many applications, the Tech II bridge was not able to provide.
The BM6010A consists of three units: a self-balancing bolometer bridge, a reference voltage generator and a Zero Voltmeter. These functional separate units are mounted together in one case and will be operated as a system.
A highlight of the bridge design is the use of four extremely stable and precise resistors, made by wekomm. These resistors are adjusted to a precision of better than 0.5 µΩ/Ω. This fact makes the measurement bridge one of the most accurate units on the market. A stability of better than 10µΩ/Ω per year guarantees even long term performance. In addition all four resistors are mounted within special temperature shields to maintain their value even under adverse conditions.
The internal reference voltage generator can be digitally controlled either via manual touch screen operation, automatic setting or via remote control commands. It’s precision provides the best accuracy available for RF power measurement. The use of the reference voltage generator as a stable voltage source in conjunction with an external voltmeter produces the most accurate measurements. This technique is particularly important at low power levels, i.e., less than 10 milliwatts.
The Zero Voltmeter is also designed to be used as a precision power stabilizer. The stabilizer has two output connectors; one with limited power output capability to drive a PIN diode leveler, the other with a 100 mA maximum output current to drive a ferrite modulator. Finally, the reference voltage generator can be used as a 0-10 volt DC source. Output impedance is less than 20 milliohms; available output current depends on the voltage setting.
These features make the BM6010A a modern reference instrument, to achieve highest possible precision in RF power measurements, making the instrument the preferable choice for this type of primary measurements.
The Wekomm engineering GmbH BM 6010A is a full replacement for the Technology Type II Power Measurement System with improved specifications. The BM 6010A was developed in cooperation with the Physikalisch Technische Bundesanstalt (PTB) and replaces the old TECH II bridges (not only there).
