HEWLETT PACKARD 4140B
외관 상태 양호하고 작동 잘됩니다
HP사의 특유의 뻑뻑한 버튼 그대로 상태 좋습니다
세부 사항 참조하세요
안전포장 택배거래 가능하나 직접 오셔서 확인후 구매하시는게 좋겠습니다.
인천입니다. (부천 인근)
가격인하 15만. 절충X.
이정도면 부품값도 안되겠습니다.

pA METER / DC VOLTAGE SOURCE
HP 4140B
The HP 4140B pA Meter/DC Voltage Source provides a stable picoampere meter with a maximum resolution of 10-15 A, and two programmable dc voltage sources. This, along with the programmable hold and step delay function, lets you make synchronized measurements on a device or on material.
Stable, high resolution current measurements: 0.001 x 10-12 A to 1.999 x 10-2 A, accuracy 0.5%, 3.5 digit display
Calculated capacitance range: 0.1 pF to 1999 pF (in two ranges)
Measurement times: ~4 ms to 2.56 s
Zero offset
Trigger: INT, EXT, HOLD/MAN
Input terminal: Triaxial
Measurement functions: I-V, C-V, I
Voltage source output range: ±100 in 10 mV steps, ramp rate 0.001 V/s to 1.000 V/s
Selectable integration times - short, medium, or long
Line filter
Automatic or manual ranging
Self test
Analog output for plotting I-V, C-V data
Selectable source current limit
Voltage sweep functions: AUTO/START, MAN (PAUSE), STEP, ABORT
Quasi-Static C-V measurements
HP-IB interface: SH1, AH1, T5, L4, SR1, RL1, DC1, DT1
Manual or programmable parameter selection and data entry
