Frequency Sweep
7
This connector accepts TTL_compatible levels and is referenced to
chassis ground (not floating ground). When not used as an input, the
Trig In connector can be configured as an output to enable the 33210A to
trigger other instruments at the same time as its internal trigger occurs.
Sync and Marker Signals
The output from the front-panel Sync connector goes “high” at the
beginning of each sweep. If you have disabled the Marker function, the
Sync signal goes “low” at the midpoint of the sweep. However, if you have
enabled the Marker function, the Sync signal goes “low” when the output
frequency reaches the specified marker frequency. The marker frequency
must be between the specified start frequency and stop frequency.
You can use the Marker function to identify a notable frequency in the
response of a device under test (DUT) – for example, you may want to
identify a resonance. To do this, connect the Sync output to one channel
of your oscilloscope and connect the DUT output to another channel.
Then, trigger the oscilloscope with the rising edge of the Sync signal to
position the start frequency on the left side of the screen. Adjust the
marker frequency until the falling edge of the Sync signal lines up with
the interesting feature in the device’s response. You can then read the
frequency from the front-panel display of the 33210A.
