This command sets the type of pattern to generate and configures the clocks. The parameter is a bit-mapped number that determines the characteristics of the motion, with the lowest bits determining the type of pattern. The code is interpreted according to the following table:
| Bit | Clear | Set |
|---|---|---|
| 7 | Internal Trigger | External Trigger on Backplane TTL input |
| 6 | Polarity of Trigger: positive edge | Polarity of Trigger: negative edge |
| 5 | No TTL out | TTL out |
| 4 | Polarity of TTL out: active high | Polarity of TTL out: active low |
| 3 | reserved | Reserved |
| 2-0 | 000 Ramp/sawtooth (code 0) 001 Triangle (code 1) (period always even number of msec) 010 Square wave (code 2) (period always even number of msec) 011 Sine wave (code 3) |
|
The TTL inputs for external triggering will individually trigger each axis as follows:
| Triggered Axis | Backplane Trigger input address | Backplane TTL out address |
|---|---|---|
| 0 | 42 | 41 |
| 1 | 44 | 43 |
| 2 | 46 | 45 |
| 3 | 48 | 47 |
SAP r=0 :A
Sets up for ramp (sawtooth) pattern, running off internal clock with no TTL outs
SAP r=129 :A
Sets up for triangle pattern, running off positive edge external TTL clock with no TTL outs.
SAP r=161 :A
Sets up for triangle pattern, running off positive edge external TTL clock with TTL outs. A 250usec pulse is put out at the start of the pattern.
Serial command<Card Addr#>TTL Y=22 will route the TTL pulses generated when BIT5 is set, to the TTL OUT0 port. Available only in Tiger firmware v3.17 and above.
