Known Issues
ˆ
Trigger Mode: If the trigger frequency changes during triggered measurement to a value
higher than 100 kHz the ACF may become distorted or the software may prompt the user to
restart it.
ˆ
ACF Fit: Sometimes the software may nd wrong parameters for the t function. The dis-
played t thus is not on the ACF. Even the t amplitude may become negative. Block and
unblock the laser beam for a second to allow the software to nd the correct t parameters.
