Signal Out
• Q-MIPS Flavor: expects external 10 k load
maximum output =
+ 6.0 V
• Isis DSP– (C31) Flavor: 10 kΩ load on SIU4 and SIU4-2
boards; they expect high impedance load
• Maximum output =
+ 6.0 V
Adjustments
• 4 each, rotary 10-position switch for channel attenuation,
screwdriver actuated, 0 to 90% signal attenuation in 10%
increments
Self-Test
(SIU4-2 only)
• Switch is numbered 0-9; on switch position 9, a ramp
waveform is generated for SIU4-2 and DSP testing. Refer
to Figure F-1 on page 117 for SIU4-2 cabling
relationships.
