Micro probes 1 MHz up to 6 GHz

MFA 01 set

Langer EMV-Technik GmbH

MFA 01 set - Langer EMV-Technik GmbH

The micro probes are used to measure magnetic fields and they have a high resolution. They measure magnetic fields up to 6 GHz, e.g. at signal conductors (150µm), SMD components (0603-0201) or IC pins. The MFA micro probes are guided by hand. An amplifier stage is integrated into the probe head. The amplifier stage (9V, 100mA) is powered via the Bias tee BT 706. It has an impedance of 50 Ohm. The micro probes are connected via the Bias tee BT 706 to a spectrum analyzer or an oscilloscope. Langer EMV-Technik GmbH includes correction lines in the delivery. With the help of the correction lines the probe output voltage is converted either into the respective magnetic field or to the current which is running through the conductor.

Resistors

Vishay Intertechnology, Inc.

Vishay Intertechnology, Inc.

A passive two-terminal electrical component that implements electrical resistance as a circuit element. In electronic circuits, resistors are used to reduce current flow, adjust signal levels, to divide voltages, bias active elements, and terminate transmission lines, among other uses. High-power resistors that can dissipate many watts of electrical power as heat may be used as part of motor controls, in power distribution systems, or as test loads for generators. Fixed resistors have resistances that only change slightly with temperature, time or operating voltage. Variable resistors can be used to adjust circuit elements (such as a volume control or a lamp dimmer), or as sensing devices for heat, light, humidity, force, or chemical activity.

Reltech Limited

Reltech Limited

The selection of the test socket is critical to the performance of a device during qualification testing where electrical bias and signals are applied. Key factors such as mechanical compatibility, operating temperature, ability to withstand high moisture levels, signal speed and lead inductance/capacitance all need to be taken into account when selecting the best socket for the test application.

Low-Noise DC Bias

-

Pulse Instruments

Pulse Instruments

Imaging devices, such as CCDs, IR FPAs, and CMOS image sensors, require DC bias with very low electrical noise to prevent contamination of the image. Image quality can also be enhanced by carefully tuning each bias voltage to extract the maximum signal/noise ratio out of an array. Pulse Instruments has decades of experience providing DC bias supplies with the flexibility required tocharacterize and test a variety of devices while maintaining the noise immunity required for satellite and astronomy applications.

SMDB - Lectrosonics, Inc.

The input section features the unique servo bias input circuitry with a standard TA5M type jack for use with electret lavaliere mics, dynamic mics, or line level signals. A DSP-controlled analog audio limiter is employed before the A-D converter. The limiter has a range of more than 30 dB for excellent overload protection and a dual release envelope that makes the limiter acoustically transparent while maintaining low distortion. The limiter recovers quickly from brief transients, with no audible side effects, and also recovers slowly from sustained high levels to keep audio distortion low while preserving short term dynamics.

DC Current Bias Supply

DC1000A

Voltech

DC1000A - Voltech

To guarantee the quality and performance of inductive components such as inductors, chokes and transformers they are tested at their real-life operating point. If the inductor is designed to carry a DC current, then its inductance must be measured with that DC current present. Until now, these measurements were made by an LCR meter connected via special interfacing to a DC bias supply available only from the manufacturer of the LCR meter. The unique NEW DC1000A can be used with any precision LCR meter and connects simply into existing test fixturing.

Four Channel Low-Noise DC Bias Card

PI-41702

-

Pulse Instruments

PI-41702 - Pulse Instruments

The PI-41702 is a four channel bipolar DC Bias supply that can provide an output current up to 100 mA per channel. The output voltage ranges from –8 V to +8 V, and this card has special filter circuitry to reduce the output noise for those applications that require a low noise bias output. Additionally there is a ‘D’ type connector that allows the introduction of laboratory type supplies to reduce the noise further. To change from using the internal power supplies to external power supplies requires repositioning jumpers. The PI-41702 also has voltage and current sense for remote measurement of the voltage and current levels.
