Input |
|||
| Inputs | Virtual null or user-set bias (±5 V) | ||
| Input offset | ±1 pA to ±1 mA adjustable DC offset current | ||
| Maximum input | ±5 mA | ||
| Noise | See table below | ||
| Sensitivity | 1 pA/V to 1 mA/V in 1-2-5 sequence (vernier adj. in 0.5 % steps) | ||
| Frequency response | ±0.5 dB to 1 MHz. Adjustable front-panel frequency response compensation for source capacitance. | ||
| Grounding | Amplifier ground is fully floating. Amplifier and chassis ground are available at rear panel. Input ground can float up to ±40 V. | ||
|
Filters |
|||
| Signal filters | 2 configurable (low-pass or high-pass) 6 dB/oct rolloff filters. -3 dB points are settable in a 1-3-10 sequence from 0.03 Hz to 1 MHz. | ||
| Gain allocation | |||
| Low noise | Gain is allocated to the front end for best noise performance. | ||
| High bandwidth | Front-end gain is reduced for optimum frequency response. | ||
| Low drift | Low bias current amplifier is used for reduced drift at high sensitivity. | ||
| Filter reset | Long time constant filters may be reset with front-panel button. | ||
|
Output |
|||
| Gain accuracy | ±0.5 % of output + 10 mV (25 °C) |
||
| DC drift | See table below | ||
| Maximum output | ±5 V into a high impedance load | ||
|
General |
|||
| External blanking | TTL input sets gain to zero | ||
| External toggle | TTL input inverts gain polarity | ||
| Rear panel biasing | ±12 VDC @ 200 mA, referenced to amplifier ground | ||
| Computer interface | RS-232, 9600 baud, receive only | ||
| Power | 100/120/220/240 VAC, 6 watts charged, 30 watts while charging. Internal batteries provide 15 hours of operation between charges. Batteries are charged while connected to the line. | ||
| Dimensions | 8.3″ × 3.5″ × 13.0″ (WHL) | ||
| Weight | 15 lbs. (batteries installed) | ||
| Warranty | One year parts and labor on defects in materials and workmanship | ||
