상세내용
| SR560 Low Noise Preamplifier | |
| Input | |
| Inputs | AC or DC coupled, single-ended or differential |
| Input impedance | 100 MΩ + 25 pF |
| Maximum input | 3 Vpp |
| CMRR | 100 dB from DC to 1 kHz (100 mVrms common mode input at 1kHz , gain=100, low noise mode. Decreases by 6 dB/octave from 1 kHz to 1 MHz) |
| Noise | 4 nV/√Hz at 1 kHz |
| Gain | 1 to 50,000 in 1-2-5 sequence. Vernier gain in 0.5 % steps. |
| Gain stability | 200 ppm/°C |
| Bandwidth | -3 dB at 1.2 MHz (typ.) |
| Flatness | ±0.3 dB to 300 kHz (gains up to 1000) |
| 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 | High Dynamic Reserve — Gain is increased after the signal filters to prevent overloading. Low Noise — Gain is increased before the filters to improve noise figure. |
| Output | |
| Maximum output | 10 Vpp into 50 Ω and 600 Ω |
| Filter reset | Long time constant filters may be reset with front-panel button. |
| DC drift | 5 µV/°C referred to input (DC coupled) |
| Distortion | 0.01 % at 1 kHz |
| Rear panel | ±12 VDC @ 200 mA referenced to amplifier ground |
| General | |
| External gating | TTL input sets gain to zero |
| Interfaces | 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 |
