Keysight (Agilent) 4145A Semiconductor Parameter Analyzer

The HP 4145A Semiconductor Parameter Analyzer is a stand-alone instrument capable of complete dc characterization of semiconductor devices and materials. It stimulates voltage and current sensitive devices, measures the resulting current and voltage responses, and displays the results in a user-selectable format (graph, list, matrix or schmoo) on a built-in CRT display. An on-board programmable calculator provides real-time calculation of voltage/current dependent parameters, such as the current gain (h FE) and transconductance(gm) of transistors, which also can be displayed on the CRT. A number of powerful graphic analysis tools-marker, cursor, line function , interpolation-enhance the HP 4145A's basic capabilities and provide fast , accurate analysis of semiconductor devices, leading to increased production yields and improved device quality. Four built-in stimulus/measurement units (SMUs) are the heart of the HP 4145A. Each SMU can be independently programmed to function as either a voltage source/ current monitor or a current source/ voltage monitor. Thus, a bipolar transistor, for example, can be completely characterized in common-base, common-emitter, and common-collector configurations without changing connections, only changing the SMUs' operating modes is required. The HP 4145A is also equipped with two voltage sources and two voltage monitors for measurements on devices having more than four terminals, such as ICs. SMU .Voltage/Current Compliance; Maximum voltage compliance: 20 V, 40 V, or 100 V, depending on the output current range. Maximum current compliance: 20 rnA, 50 rnA, or 100 rnA, depending on the output voltage range. Compliance setting resolution: same as current and voltage output/measurement resolution. Maximum current compliance resolution, however, is 50 pA. Compliance accuracy: voltage compliance accuracy is the same as voltage output/measurement accuracy. Current compliance accuracy is current output/measurement accuracy ± (1 % of range + 10 pA. Voltage Sources (Vs) Characteristics; Number of sources: two. Output resistance: <=0.2 ohm. Maximum capacitive load: 1000 pF. Display: CRT size and screen resolution 152.4 mm (6 inch) diagonal; 2048 x 2048 points. Display modes: Graphics, Schmoo, List, Matrix, and Time Domain.

*This is a Web introductory price for one calibration of the Keysight (Agilent) 4145A. Price does not in most cases include measurement performance data. Pricing does include NIST traceable calibration and issue of a calibration certificate and calibration label. Pricing may vary slightly due to volume and location of laboratory supporting calibration. Volume pricing may apply. On-site fees may apply depending on logistics, location and volume of work to be completed during the visit.

dBc
dBc (decibels relative to the carrier) is the power ratio of a signal to a carrier signal, expressed in decibels. If the dBc figure is positive, then the relative signal strength is greater than the carrier signal strength. If the dBc figure is negative, then the relative signal strength is less than carrier signal strength.

Load Regulation
Load regulation is the capability to maintain a constant voltage (or current) level on the output channel of a power supply despite changes in the supply's load (such as a change in resistance value connected across the supply output).

Power Linearity
When changing the power level and measuring the differences (in dB) between actual and displayed power levels, the power linearity is ± half the span (in dB) between the maximum and the minimum value of all differences.

Settling Time
Settling time of an output device is the time elapsed from the application of an ideal instantaneous step input to the time at which the amplifier output has entered and remained within a specified error band, usually symmetrical about the final value.
