APPENDIX A

REMOTE PROGRAMMING

Introduction

The SR560 is equipped with a standard DB-

25RS-232C connector on the rear panel for remote control of all instrument functions. The interface is configured as listen-only, 9600 baud DCE, 8-bit, no parity, 2 stop bits, and is optically isolated to prevent any noise or grounding problems.

Up to four SR560 amplifiers can be connected in parallel to the same RS-232 interface. Units sharing the same interface must have a unique address as set on dip switch SW601, accessible through the bottom cover of the unit. To set an instrument to one of the four available addresses, adjust positions one and two of dip switch SW601 as follows:

Commands

The following commands are obeyed by all SR560’s that are addressed to listen. The LALL, LISN, and UNLS commands are always obeyed and control the address status of the SR560. Commands must end with a carriage return and line feed <CR> <LF>.

BLINK i Operates amplifier blanking.

i = 0 = not blanked, 1 = blanked

CPLGi Sets input coupling.

I = 0 = ground, 1 = DC, 2 = AC

DYNR i Sets dynamic reserve.

i = 0 = low noise, 1 = high DR, 2 = calibration gains (defaults)

FLTM i Sets filter mode. i = 0 = bypass,

 

1

= 6 dB low pass,

 

2

= 12 dB low pass,

 

3

= 6 dB high pass,

 

4

= 12 dB highpass,

 

5

= bandpass

GAIN i

Sets the gain.

 

i = 0 – 14 = 1, 2, 5, … 50 k gain

HFRQi

Sets highpass filter frequency.

 

I = 0 – 11 sets frequency = 0.03

 

Hz to 10 kHz

INVT i

Sets the signal invert sense.

 

i = 0 = non-inverted,

 

1

= inverted

LALL

Listen all. Makes all attached

 

SR560’s listeners.

LISN i

Listen command. Makes

 

SR560 with address i (0,1,2,3)

 

a listener.

LFRQ i

Sets lowpass filter frequency.

 

i = 0 – 15 sets frequency

 

= 0.03 Hz to 1 MHz

ROLD

Resets overload for ½ second.

SRCE i

Sets the input source.

 

i = 0 = A, 1 = A-B, 2 = B

UCAL i

Sets the vernier gain status.

 

i = 0 = cal’d gain,

 

1

= vernier gain

UCGN i

Sets the vernier gain to i %.

 

i = 0 to 100

UNLS

Unlisten. Unaddresses all

 

attached SR560’s.

*RST

Reset. Recalls default settings.
