7.5.4 Set Frequency Converter Control
If the camera enables the frame trigger or the line trigger, you can select
Frequency Converter
as
trigger source. The hardware signal trigger or shaft encoder control signal can be converted into the
signal frequency of frame trigger or line trigger by c
amera’s frequency converter module.
The frequency converter module includes
PreDivider
,
Multiplier
and
PostDivider
. The
signal, after being processed by these 3 modules, will be the camera final trigger signal.
⚫
PreDivider
The input signal first enters the PreDivider module, which reduces source signal frequency via
integer division, and then the signal is sent to the Multiplier module.
The PreDivider module reduces periodic jitter on the input signal, and signals above 100 kHz must
go through the PreDivider module to reduce the frequency (since the Multiplier can only receive
signals in the range of 10 Hz to 100 kHz frequency range). The periodic jitter of shaft encoder signal
is accepted.
⚫
Multiplier
After the signal is processed by the PreDivider, it is sent to the Multiplier. The Multiplier
multiplies the signal by an integer to increase its signal frequency, and then the signal is sent to the
PostDivider.
Parameter can be set as rising or falling edge. If a rising edge is set, each rising
edge of the
signal coming from the PreDivider will be locked to match the signal of the rising
edge, and
vice versa.
During this process, make sure do not increase signal frequency too much: avoid trigger signal
frequency above the maximum line rate of the camera. Even if a smaller multiplier is selected, an
excessively high frequency may be generated in the frequency adjustment, exceeding the maximum
line rate of the camera.
⚫
PostDivider
PostDivider reduces signal frequency via an integer factor, and uses the newly generated
frequency signal as the camera's trigger signal.
