9.1.1.22.6 Command: tbval
Command
tbval,slew-rate,pos,duration
Description
Set the parameters of the current row of the table-driven generator by storing them into the
device's EEPROM. On success, the index of the current row is incremented automatically.
The index of the current row of a running or stopped table-driven generator is affected, but the
rows of a running or stopped table-driven generator are not affected
Responses
ok
on success
nok
on failure
Query
tbval
Description
Get the parameters of the current row of the table-driven generator by retrieving them from the
device's EEPROM. On success, the index of the current row is incremented automatically.
The index of the current row of a running or stopped table-driven generator is affected.
Responses
tbval,slew-rate,pos,duration
on success
nok
on failure

9.1.1.23 Function Generators
Every function generator has the following ordered parameter set:
1. Frequency in Hz.
2. Initial phase angle in degrees.
3. Amplitude in %.
4. Offset in %.
5. Duty cycle in %.
Amplitude and offset, both in %, refer to the range of the piezoelectric voltage (in V) while the drift
compensation is inactive and refer to the range of the position (in µm, mrad or µrad) while the drift
compensation is active. The parameterized forms of the commands of the function generators initialize the
output only. The output starts after executing the command "
start,0,func
".
Note:
Even if a parameter is required in requests and contained in responses, it may be unused in the command
execution. An unused parameter is grayed out in the command-specific description.

9.1.1.23.1 Command: sin
Command
sin,frq,phase,amp,offs,duty
Description
Set the parameters of the sine function generator by storing them into the device's EEPROM.
A running or stopped sine function generator is not affected.
