Initiates an internal user calibration for the 100MHz reference oscillator.
This command is valid with and without the Low Phase Noise and Ultra High Stability option.
This calibration will generate an error if there is no 10MHz reference or if the unit cannot lock to the 10MHz reference.
The Low Phase Noise and Ultra High Stability calibration requires an external 10 MHz or 1PPS input. This calibration optimizes for an acceptable frequency error between the 100 MHz and the external input. This calibration will generate an error if initiated while the unit is not locked to an external 10 MHz or 1PPS.

Sweep Generation
Description:
Selects stepped frequency sweeps for sweep1. Setting the sweep generation may affect sweep parameters dwell, time, dwell auto, and time auto. Related commands:
Sets the number of points in a stepped frequency sweep or stepped power sweep. Points and step are coupled values. Entering the value for one will cause the other to be recalculated, per the following formula: points = (span / step) + 1. Entering a new value for either parameter will not change the span. An error will be generated if the points entered results in a calculated step size less than the minimum resolution for a stepped frequency sweep or a stepped power level sweep. An error will also be generated if the entered step size results in the number of points exceeding its maximum. Note: The absolute maximum number of frequency points is 65535, and the absolute maximum of power points is calculated using: absMax = (([:SOURce]:POWer? MAX - [:SOURce]:POWer? MIN) / [:SOURce]:POWer:SPAN? MIN) + 1 Related commands:
SWEep1: Select from 4 frequency ranges, F1-F2, F3-F4, F5-DF, F6-DF, where DF represents delta F. Input without '-' i.e. SWEep1:RANGe F1F2. SWEep2: select from 5 power ranges, L1-L2, L3-L4, L5-L6, L7-L8, L9-L0. Input without '-' i.e. SWEep2:RANGe L1L2. Setting a sweep range may affect sweep parameters start, stop, center, span, step size, and points.
When applying a Frequency Range Selection which utilizes the Delta Frequency (F5-DF, F6-DF), if the Delta Frequency is configured to a value which would result in a Start Frequency less than the minimum CW Frequency or a Stop Frequency greater than the maximum CW frequency, an execution error will be reported.
Sets the sweep time for sweep1 or sweep2. When :SWEep<n>:TIME <param> is implemented, :SWEep<n>:TIME:AUTO is set to OFF. :TIME, :DWELl, :SPAN, :STEP, and :POINts are all interrelated.

:TRIGger:TYPE <AUTO|SINGle|EXTernal|MANual>
:TRIGger:TYPE?
Title:
Trigger Type
Description:
The Trigger Type represents a convenience command to set the following settings: Trigger Mode, Initiate Continuous, and Trigger Source.
The following represent the Trigger Types and the valid configurations of the associated settings:
(TRIG:TYPE = TRIG:SOUR, INIT:CONT, TRIG:MODE) AUTO = IMMediate, ON, [SWEep]|POINt SINGle = BUS, ON, SWEep EXTernal = EXTernal, ON, SWEep MANual = [BUS]|EXTernal, ON, POINt
Settings with multiple values are valid values for that Trigger Type and the value enclosed in the square brackets ([]) is the value that the relevant setting will be set to upon setting the relevant Trigger Type.
If a value is changed for a dependent setting and the collection of dependent setting values no longer matches a valid configuration, the Trigger Type query will return a value of REMote. The REMote condition can be resolved by setting the Trigger Type or modifying the dependent settings so that they match a valid configuration.
