Demo #6 - Using RCal as a CW Source and Comb Generator

RCal now supports the Calibrator Control feature, which allows you to use RCal to generate both
CW and comb signals with adjustable frequencies and comb spacings. The power of the output
signal cannot be adjusted within the X-Series software. External attenuators can be used to adjust
the power as needed. CW output power is normally greater than -10 dBm below 40 GHz and
normally greater than -30 dBm above 40 GHz. RCal calibrator control can be accessed within the
X-Series front panel through Input/Output > Calibrator Control.
Calibrator Control Options:
— Cal Source: Selects the desired RCal module to control
— Output: Toggles the RCal RF output state
— Frequency: Sets the RCal signal frequency
— Frequency Reference: Selects the frequency reference used by the RCal module. Using the
External 10MHz reference is highly recommended.
— Signal: Selects between a CW tone or a comb signal for the RCal output signal type
— Comb Spacing: Select the spacing of the frequency comb when using a comb signal
The table below gives minimum and maximum frequency and comb spacing options when using
Calibrator Control:
