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.

Pulse Instruments

PI-41701 - Pulse Instruments

The PI-41701 is a dual 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 features programmable current limits with LED indicators and software interrupt to show/alert the user if the channel is in current limit. This card has special filter circuitry to reduce the output noise for those applications that require a low noise bias output.

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.

Pulse Characterization Sensors

MKS Ophir

MKS Ophir

Pulse Characterization Sensors provide the ability to see and measure the temporal characteristics of pulsed and CW laser beams. Ophir Fast Photodiode Detectors are designed to convert optical signals into electrical signals which are then measured with third-party instrumentation such as oscilloscopes and spectrum analyzers. Accessories are available to connect to IS6 integrating spheres or fiber optic cables. Attenuating filter accessories are also available to increase their dynamic range. Different models offer silicon, UV enhanced silicon and InGaAs PIN photodiodes, covering a combined spectral range of 193 nm to 1700 nm. Rise times range from 25 picoseconds to 3 nanoseconds. The fast rise times are achieved by an internal reverse bias voltage circuit. Power is supplied by internal batteries and/or an external power supply depending on the model. Detectors should be connected to a 50Ω impedance in order to maintain their nominal rise times. They can be connected to higher impedance loads, but this will result in a significant increase in the rise time. If higher output voltage is required, it is recommended to connect the detector to a trans-impedance amplifier with an Input impedance of 50Ω

RF Amplifiers Bias Controllers

Analog Devices Inc.

Analog Devices Inc.

RF amplifier bias controllers generate a regulated drain voltage and actively adjusts the gate voltage of an external amplifier to achieve constant bias current. It can be used to bias any enhancement and depletion type amplifier operating in Class-A regime with drain voltages (VDRAIN) as specified. These devices achieve excellent bias stability over supply, temperature and process variations, and eliminates the required calibration procedures used to prevent RF performance degradation due to such variations.

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.
