    Abstract: A scale control method provides fine scale control in a measurement instrument and also provides scale control spanning wide adjustment ranges. The method detects the presence of the user input to a control sensor and establishes an acceleration factor for the input based on a rate at which events are generated by the control sensor. The acceleration factor modifies a defined scale step size that has a correspondence to the events generated by the control sensor. The defined scale step size, as modified by the acceleration factor, is added to a prior scale to establish a present scale. The present scale and prior scale are used to select a detent value from a series of detent values and to determine if a detent is applicable. When a detent is applicable, the present scale is set to the selected detent value and control of the scale parameters is then determined by this detent value. When the detent is not applicable scale parameters are adjusted according to the defined step size as modified by the acceleration factor.

    Abstract: A method automatically scales a sampled representation of a waveform applied to a sampling system, regardless of the nature of the waveform. The method, implemented within a digital oscilloscope or other type of sampling system, achieves amplitude auto-scaling from samples of the applied waveform acquired when the sampling system is un-triggered. The method then determines the nature of the applied waveform based on the number of acquired samples within an intermediate amplitude band and the number of amplitude transitions across the amplitude band. Records are then taken with the sampling system triggered and the occurrence of alternative designated events, based on the nature of the waveform, is detected within the records. Time offset and time gain are adjusted based on a first occurrence and a second occurrence of the designated event.

    Abstract: A phase-lock loop for a swept synthesized source in which hysteresis, tuning nonlinearity, and drift over time and temperature of an oscillator incorporated into the swept synthesized source are compensated. The tuning current to the oscillator is initialized to zero to eliminate hysteresis effects. Then, the pretune current is set to produce the minimum operating frequency of the oscillator. Next, the main phase-lock loop is closed, and a low-frequency synthesizer is swept to in turn sweep the oscillator over a selected frequency span. If the selected frequency span extends over other frequency bands, the oscillator is swept to the maximum frequency of the present band and held at this frequency by a track and hold circuit. The main phase-lock loop is opened, the low-frequency synthesizer is re-initialized, the main phase-lock loop is again closed, and the low-frequency synthesizer is swept again. Each frequency band is crossed in a similar manner until the selected frequency span is swept. In order to improve phase-noise and transient response performance of the low-frequency synthesizer, a phase-lock loop speed-up and stability enhancement circuit comprising a zener diode connected across a passive lag-lead network is incorporated. Pretune calibration for the swept synthesized source is also provided.
