Settings on the Agilent Synthetic Instrument GUI

Frequency

Sets the center frequency or frequency offset of the N8201A performance downconverter.

Center Frequency

Sets the center frequency while the span remains constant. The frequency range of the N8201A performance downconverter is 3 Hz to 26.5 GHz plus the frequency offset. If the External Mixer Enabled equals External, the frequency range is 3 Hz to 335 GHz.

Frequency Offset

Enables you to input a frequency offset value to account for external frequency conversions. This value is added to the display readout of the marker frequency, center frequency, start frequency, stop frequency, and all other absolute frequency settings. Limits are −500 THz to 500 THz.

Frequency List

Sets up a list of frequencies for the instrument to step through. The list begins with Start Frequency, and adds the Step Frequency until the Stop Frequency is reached. The next trigger causes the list to be repeated.

Disabled Prevents a frequency step sequence from being initiated.

Start Sets the first frequency that will be swept on a list sweep.

Stop Sets the last frequency that will be swept before the list is repeated.

Step Sets the difference between successive swept frequencies.

Trigger Setup Sets up the trigger that will be used to step through the frequency list.

Trigger Source

Sets the source of triggers. When the specified trigger occurs, the instrument will move to the next frequency in its frequency list. Possible values are:

EXT - TTL LX10 LX11 LX12 LX13

LX14	LX15	LX16	LX17	LAN0
LAN1	LAN2	LAN3	LAN4	LAN5
LAN6	LAN7	ALARM0
