Technical characteristics of the outputs
The following table shows an overview of the technical characteristics of the individual
outputs.
Frequency range
(period duration)
Accuracy of 10 to <= 100 kHz (100 to
the pulse > = 10 µs)

ms to > 100 µs)
10 to < 100 Hz (0.1 s to

1 to <10 Hz (1 to > 0.1 s)
0.1 to < 1 Hz (10 to >1 s)

With sourcing outputs, it must be taken into consideration that falling edges can be delayed as compared to rising edges
1)
depending on the load. The on-load factor can therefore be falsified. Consider using a high-speed output if the load at
the output is greater than 240 Ω.
The frequency has a basic accuracy of ±100 ppm with a resolution of 0.3638 mHz.

Standard outputs are affected by jitter during generation of frequencies. The set period duration is not adhered to in
3)
every period, but it is adhered to on average over several periods.
