4.20 Automatic Operation

The Model 4500B can make up to 15 automatic measurements. The available measurements depend upon the operating mode

and the characteristics of the displayed waveform. Pressing the Text system key will display all of the available automatic

range will be indicated by up arrows " " and under range by down arrows "v ".

A single channel instrument can make the following list of measurements on Channel 1, External Trigger 1, Memory channel

1 and Mem channel 2. For a dual channel instrument add Channel 2 and External Trigger 2. Memory channel measurements

correspond with the type of waveform stored.

AUTOMATIC MEASUREMENTS – PULSE MODE

The information displayed in the Pulse mode text report is based on the data captured. Parameters such as pulse width,

period, and repetition frequency, can only be displayed if there are a sufficient number of pulse transitions on the display. For

pulse width, there must be at least two pulse transitions; for pulse period, duty cycle and repetition frequency there must be

three. If the number of tran--.-
