202026 <location>Function generator: Pulse width too wide
Reaction: NONE
Acknowledge: NONE
Cause: The selected pulse width is too high.
The pulse width must be less than the period duration.
See also: p4822
Remedy: Reduce pulse width.
See also: p4821, p4822
202030 <location>Function generator: Physical address equals zero
Reaction: NONE
Acknowledge: NONE
Cause: The specified physical address is zero.
See also: p4812
Remedy: Set a physical address with a value other than zero.
See also: p4812
202040 <location>Function generator: Impermissible value for offset
Reaction: NONE
Acknowledge: NONE
Cause: The value for the offset is higher than the value for the upper limit or lower than the value
for the lower limit.
See also: p4826
Remedy: Adjust the offset value accordingly.
See also: p4826, p4828, p4829
202041 <location>Function generator: Impermissible value for bandwidth
Reaction: NONE
Acknowledge: NONE
Cause: The bandwidth, referred to the time slice clock cycle of the function generator has either
been set too low or too high.
Depending on the time slice clock cycle, the bandwidth is defined as follows:
Bandwidth_max = 1 / (2 * time slice clock cycle)
Bandwidth_min = Bandwidth_max / 100000
Example:
Assumption: p4830 = 125 µs
--> Bandwidth_max = 1 / (2 * 125 µs) = 4000 Hz
--> Bandwidth_min = 4000 Hz / 100000 = 0.04 Hz
Note:
p4823: Function generator bandwidth
p4830: Function generator time slice cycle
See also: p4823, p4830
Remedy: Check the value for the bandwidth and appropriately adapt.
202047 <location>Function generator: Invalid time slice clock cycle
Reaction: NONE
Acknowledge: NONE
Cause: The time slice cycle selected does not match any of the existing time slices.
See also: p4830
Remedy: Input an existing time slice cycle. The existing time slices can be read out via p7901.
See also: r7901
202050 <location>Trace: Start not possible
Reaction: NONE
Acknowledge: NONE
