技术参数
(maximum or minimum as applicable unless otherwise noted)
灵敏度 10-3 to 10-11 ampere/volt with nine decade current gain ranges.
增益 Output gain multiplier varies sensitivity in 3 steps,X0.1,X1.0 and X10, for optimum dynamic range and overload capability.
增益精度 ±2% of reading (10-3 to 10-9 ampere/volt ranges); ±3% of reading (10-9 thru 10-11 ampere/volt ranges).
输入电流补偿 Less than 0.5X10-13 ampere @ 50℃.Typically 1×10-4 @25℃.
输入压降 Less than 200 microvolts, 10-5 to 10-11 ampere/volt ranges.
上升时间（低通滤波器） Front Panel adjustable from 10 microseconds to 1 second in a 1-3-10 sequence; IN position rise time is less than 5 microseconds. Standard rolloff is 12 dB/octave. Jumper option for 6 dB/oct when 1211 is applied in feedback control loops.
输出：
a) 600Ω outputs (2)
b) Lo-Z output (to 25 mA, 50Ω)
c) Unity gain output(X1)
输出电压 22 Vpp into 1 K load (Lo-Z out)
输出端极性 Unity gain (X1) Non inverted
Lo-Z（50Ω） Inverted
600Ω Inverted
输出稳定性 Output voltage offset stability better than 0.003% per ℃.
归零设置 Input offset nulling. Used to adjust for precisely zero bias voltage on detectors such as photovoltaic diodes. Alternatively, can adjust for zero d.c. offset on output.
偏置 Zero to ±5 volts, adjustable and polarity-selectable with rear panel vernaier(10-turn) and switch. Stability is 100ppm/℃.
门控 TTL-compatible logic 0 or switch closure to ground (rear panel BNC input) provides gated operation of preamplifier signal path; maximum gating frequency is 5 kHz.
功率 100 to 130 or 200 to 260 VAC (switch-selectable), 50-60 Hz, 10Watts.
尺寸 90×215×380(3.5＂high×8.5＂wide×15＂deep)
