Product Overview:
The SR570 is a low noise current preamplifier capable of achieving current gains of up to 1 pA/V. High gain and bandwidth, low noise, and many convenient features make the SR570 ideal for a variety of photon, low temperature, and other measurements.
Product features:
Two rear panels optically isolated TTL inputs provide additional control over the SR570. The blanking input lets you quickly turn the instrument's gain off/on, which is useful for preventing front end overload. Switching the input in response to the TTL signal inversion gain symbol allows you to perform synchronous detection using the chopper signal.
Three rechargeable lead-acid batteries provide up to 15 hours of battery-operated operation. When the device is connected to the line, the internal battery charger automatically charges the battery. The charger senses the state of the battery and adjusts the charging rate accordingly. Two rear panel LED indicators indicate the battery's charging status. When the battery is discharged, they automatically disconnect from the amplifier circuit to avoid damaging the battery.
