A. ITH2825A High Speed LCR Meter Features ■ Ultrahigh measurement speed: 15ms (frequency>100Hz) ■ 240*64 dot-matrix LCD display ■ Humanization operation board ■ 10 typical frequencies from 50Hz to 100kHz ■ Programmable test level from 10mVrms to 1.0Vrms ■ Built-in bias voltage source from -5VDC to +5VDC or max. DC bias current source of 200mA ■ Accurate load correction ■ 5 selectable source impedance modes ■ List sweep function for up to 4 frequencies, signal levels and DC bias levels ■ Measurement signal V/I monitor function ■ Transformer parameter measurement function ■ Built-in 10-bin comparator, sorting and bin counter ■ Hi/Go/Low comparison function and beeper alarm ■ Key lock function ■ Automatic LCZ function ■ 10 sets of measurement parameters saved ■ Measurement parameters automatically loaded at the time of turning on instrument ■ Handler interface compatible with Agilent 4263B ■ IEEE-488 control command compatible with Agilent 4263B Multi selectable signal source impedance modes ■ Different LCR meters get different measurement results because of different impedances. TH2825/TH2825A provides 5 selectable impedance modes to meet different needs, to ensure the consistency of measurement results between different meters. Constant-voltage mode suitable for measurement of multilayer ceramic capacitor(MLCC) Constant-voltage mode suitable for measurement of multilayer ceramic capacitor (MLCC) ■ MLCC is rather sensitive to signal test level. And TH2825/ TH2825A can measure large-amount MLCC with constant high-level signal. It is allowed to measure MLCC of 30pF at constant 1kHz/1Vrms, and MLCC pf 300pF at constant 100Hz/1Vrms. Powerful transformer measurement function ■ TH2825A has the function of measuring transformer. Using special transformer test fixture, turns ratio (N, 1/N), mutual inductance (M), primary and secondary inductances (LA, LB), primary and secondary DC resistances (DCR2) can be measured without changing test cable mode. With adjustable DC bias current up to 200mA (TH2825/TH2825A both have), the meter can conveniently measure communication transformer and choke with small power. Interface being compatible with famous meters ■ HANDLER, GPIB interfaces and GPIB interface command are completely compatible with Agilent 4263B, which help build conversion with 4263B. Specifications TH2825A Brief Introduction ■ TH2825A high-speed LCR meter is new-generation component parameter measurement instrument. It offers high measurement speed up to 20times/second, 10 frequencies from 40Hz to 100kHz, programmable signal level from 0.01V to 1.0V with step of 10mV, 5-digit resolution, multi source resistance selections, and strong measurement functions. So it is suitable for quality control on production line, incoming inspection, and component design. High measurement speed ■ This instrument, using the most advanced technology in the field, has the strong measurement function which is compatible with advanced products in the world. It provides incomparable measurement speed up to 20 times/second, which solves the problem of slow measurement speed at low frequency. So it is ideal instrument to perform high-speed measurement for electrolytic capacitor, ceramic capacitor, and transformer. Measurement function
