•G - 140 to 220 GHz

•Y - 170 to 260 GHz

•J - 220 to 325 GHz

Harmonic A user defined frequency band. Limits are −50 to −1 or 1 to 50.

Mixer Bias Turns on/off the mixer bias and adjusts an internal bias source for use with external mixers. The bias signal is present on the center conductor of the IF INPUT connector on the front panel.

Bias Level Sets the bias level. Limits are −10 mA to 10 mA.

Calibration

Accesses the Align system and immediately executes an alignment cycle of all the subsystems (Align RF, Align IF, Align ADC, and Align Current Sys Gain). The instrument will change any current system settings currently underway, perform the full alignment, and then return to the current system settings that were in place before the calibration began.

A calibration nominally takes 35 seconds to perform.

The N8201A downconverter will meet its specifications when:

•It is stored a minimum of two hours within the operating temperature range and turned on for at least 30 minutes followed by a calibration.

•When a calibration has been performed within the past 24 hours or when the temperature changes 3 °C.

•The front panel 1st LO OUT connector is terminated with a 50 ohm load.

Events (Settling Events and Event Logging)

Settling Event

Allows you to define the parameters of the Settling Event. The Settling Event has a positive edge when the frequency is set and a negative edge when the system is stabilized.

Settling Channel

Selects the channel to configure. Possible values are:

LXI0	LXI1	LXI2	LXI3
LXI4	LXI5	LXI6	LXI7
LAN0	LAN1	LAN2	LAN3
LAN4	LAN5	LAN6	LAN7
