1.  For output frequencies > 330 MHz, the trigger rate is ½ of the output frequency. In pattern mode
with bit rate > 330 MBit/s, the trigger rate is ½ of the output frequency. If a frequency sweep or a
FSK frequency exceeds 330 MHz, the trigger rate is ½ of the output frequency.
Logical strobe signal
The logical strobe signal is an internally generated signal that can be routed to the
BNC connector of Sync Out A or Sync Out B. For the two-channel instrument, the
logical strobe signal is generated for both, channel 1 and channel 2.
The logical strobe signal has a different function, depending on the mode of operation.
If no advanced mode is selected, the logical strobe signal is constant low.
In advanced mode internally/ externally triggered or gated burst, the logical strobe
signal provides a signal indicating the duration of a burst. The rising edge of the logical
strobe signal is synchronized to the start of the first waveform period in a burst. The
falling edge is synchronized to the start of the last waveform period in the burst.
In advanced mode sweep with the frequency marker off, the logical strobe signal is a
pulse with half of the duration of the sweep. The strobe signal goes high at the beginning
of the sweep.
In advanced mode sweep with the frequency marker on, the logical strobe signal goes
high at the beginning of the sweep and goes low at the marker frequency.
In advanced mode internally/externally modulated (AM, FM, FSK, PM, PWM), the
logical strobe signal is the analog modulation waveform.
In pattern mode (block mode = On), the logical strobe signal goes high at the beginning
of the pattern and goes low at the last bit of the pattern. Refer to the User Guide for
more details.
