OPERATION AND CONTROLS

turn off and the yellow "MAINTAIN" LED will be on full brightness.

Blanking Input

The blanking input accepts a TTL-level signal and grounds the amplifier signal path after the front end for as long as the input is held high. The response time of the blanking input is typically "on" 5 µs after the rising edge and "off" 10 µs after the falling edge.

RS-232 Interface

The RS-232 interface connector allows listen-only communication with the SR560 at 9600 baud, DCE. Communication parameters should be set to 8 bits, no parity, 2 stop bits. Data sent must be delimited by <CR> <LF>. All front panel functions excluding power and blanking, are available over the RS-232 interface. For more information on programming and commands, see Appendix A: Remote Programming.

BATTERY CARE AND USAGE

The SR560 can be powered from either an AC power source or from three 12 V, 1.9 Amp-hour maintenance-free sealed lead- acid rechargeable batteries. Integral to the SR560 is an automatic battery charger, along with battery protection and charge indication circuitry.

Recharging

During battery operation, the front panel BATT LED will change from green to red to indicate that the batteries are low and require charging. For the longest battery life, the batteries should be immediately charged by plugging the unit into AC power whenever the BATT indicator lights red. Internal protection circuitry will disconnect

the batteries from the amplifier if the unit is operated for too long in the low battery condition. This protects the batteries from permanent damage, which could occur if they were to remain connected to a load while dead.

The internal battery charging circuitry of the SR560 will automatically charge dead batteries at a quick rate until they are approximately 80% charged. The charge rate is then lowered to a level that is safe for maintaining the batteries. During AC operation, the batteries will be in this "maintain" charge condition indefinitely, and will suffer no degradation from prolonged charging. The sealed lead-acid batteries used in the SR560 differ in this respect from nickel-cadmium batteries, which do suffer shortened lifetimes due to overcharging. The sealed lead-acid batteries will provide the longest service life if they are not allowed to discharge too deeply and if they are charged immediately after use.

Battery Care

WARNING: As with all rechargeable batteries, for safety reasons the chemical recombination processes within the cells require that the batteries be allowed to vent non-corrosive gases to the atmosphere. Always use the batteries in an area with adequate ventilation.

As with all instruments powered by rechargeable batteries, the user must take some precautions to ensure long battery life. Understanding and following the precautions outlined below will result in a long operating life for the batteries in the SR560.

The SR560's internal lead-acid batteries will have a variable service life directly affected by THE NUMBER OF DISCHARGE CYCLES, DEPTH OF DISCHARGE AND AMBIENT TEMPERATURE. The user should follow these simple guidelines below to ensure longest battery life.
