DIN Keyboard

The following table lists signals at the DIN keyboard connector (A10 P200). A description of each signal follows the table.

Signal Name	Pin
KEYCLK	1
KEYDAT	3
+5 V	4
Logic Gnd	2
Not Used	5

KEYCLK	Key Board Clock — This clock synchronizes the transfer of keyboard data from the external
	keyboard to the A10 Rear Panel assembly.
KEYDAT	Key Board Data — This is 8-bit serial data from an external keyboard to the A10 Rear Panel
	assembly .

Source Output

The source output is routed from P3 on the A5 Analog assembly through an SMB cable to P201 on the A10 Rear Panel assembly. The A10 Rear Panel assembly then routes the source signal to the Source BNC connector. In two channel analyzers, the source output is also routed from P2 on the A5 Analog assembly through an SMB cable to P11 on the A12 BNC assembly. The A12 BNC assembly then routes the source signal to the Source BNC connector on the front panel. The source signal can be random noise, burst random noise, periodic chirp, burst chirp, pink noise, or fixed sine. The signal’s amplitude range is ±5 Vpk.

Tachometer Input

The A10 Rear Panel assembly converts the signal connected to the Tachometer BNC connector to a TTL representation of the tachometer input (BTACH).

External Trigger Input

The A10 Rear Panel assembly buffers the signal connected to the External Trigger BNC connector. The maximum trigger input level is ±25 Vpk. The minimum trigger pulse width is 600 ns and the maximum trigger pulse rate is 800 kHz.
