74 Agilent N8201A Performance Downconverter Synthetic Instrument Module, 3 Hz to 26.5 GHz
3 Using the Agilent Synthetic Instrument GUI
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
