25. Amplitude Key
Press this hardkey to activate the power level amplitude function so that you can change
the amplitude of the RF output.
26. Frequency Key
Press this hardkey to activate the frequency function so that you can change the frequency
of the RF output.
27. Save Key
This hardkey lets you save up to 100 different instrument states in a combination of 100
memory registers and 10 register sequences. The number of states you can save, however,
is limited by the size of whatever else is stored in the file system.
28. Menu Keys
These hardkeys provide access to the signal generator’s primary functionality. Press these
keys for access to softkey menus where you can configure modulations, step and list
sweeps, and various frequency and power capabilities.
29. Incr Set Key
Press this hardkey to toggle between the current active function and the increment size for
that function. With increment size selected, you can change the current increment value.
30. Recall Key
This hardkey lets you restore any instrument state that you previously saved in a memory
register. You can save up to 100 different instrument states in a combination of 100
memory registers and 10 register sequences. The number of states you can save, however,
is limited by the size of whatever else is stored in the file system.
31. DATA Input Connector
The TTL/CMOS compatible DATA connector accepts an externally supplied data input for
digital modulation applications. The expected input is a TTL or CMOS signal where a
CMOS high is equivalent to a data 1 and a CMOS low is equivalent to a data 0.
The maximum input data rate is 50 Mb/s if the user supplies the data. If the signal
generator is supplying any of the data, the maximum rate is 5 Mb/s. The leading edges
must be synchronous with the DATA CLOCK rising edges. The data must be valid on the
DATA CLOCK falling edges. The damage levels are > +8 and < −4V.
This female BNC connector is provided on instruments with Option UN8. It is also present
but not functional on instruments with Option UND. On instruments with Option 1EM,
this input is relocated to a rear panel SMB connector.
