SIGNAL GENERATOR
Document Type and Number:
Japanese Patent JP3486878
Kind Code:
B2
Abstract:
PURPOSE: To confirm waveform information in the case of sweeping by providing a sweep value read circuit reading a content of a sweep memory and a sweep value storage memory storing read data to store the outputted sweep value.
CONSTITUTION: When a sweep frequency monitor switch is depressed, the selection of a sweep frequency monitor is stored in a display item memory 6 and a sweep value read circuit 16 reads sequentially data from a sweep memory 3 and stores the data to a sweep value memory 17. Furthermore, a display control circuit 4 reads a sweep frequency stored in the memory 17 and the frequency is displayed on a numeral display section and a sweep frequency monitor switch is displayed as an inverted image. As a result, the circuit 16 reading the content of the sweep memory 3 and the memory 17 storing the read data are provided to store the sweep value actually outputted to confirm waveform information in the case of sweeping.
