The receiver will meet its specifications when: – It is within its calibration cycle – Under auto couple control, except when Auto Sweep Time Rules = Accy – Signal frequencies < 10 MHz, with DC coupling applied – The receiver has been stored at an ambient temperature within the allowed operating range for at least two hours before being turned on – The receiver has been turned on at least 30 minutes with Auto Align set to normal, or, if Auto Align is set to off or partial, alignments must have been run recently enough to prevent an Alert message; if the Alert condition is changed from "Time and Temperature" to one of the disabled duration choices, the receiver may fail to meet specifications without informing the user.
