Variable resolution oscilloscope

An electronic test instrument, comprising:

• a display;
• a plurality of digitizers;
• multiple acquisition channels;
• one or more processors;
• one or more computer-readable devices including instructions that, when executed by the one or more processors, cause the electronic test instrument to perform operations that include:
• receiving, by the electronic test instrument, user input that specifies user-configurable settings of the electronic test instrument;
• identifying, by the electronic test instrument, hardware characteristics of the electronic test instrument;
• determining, by the electronic test instrument, multiple different arrangements of the plurality of digitizers that result in valid configurations of the electronic test instrument accounting for when the electronic test instrument is configured according to the user-configurable settings specified by the user input and has the hardware characteristics of the electronic test instrument, wherein:
• (i) a first arrangement of digitizers from the multiple different arrangements of the plurality of digitizers specifies a first number of digitizers interleaved horizontally and a second number of digitizers interleaved vertically,
• (ii) a second arrangement of digitizers from the multiple different arrangements of the plurality of digitizers specifies a third number of digitizers interleaved horizontally and a fourth number of digitizers interleaved vertically, and
• (iii) the first arrangement of digitizers is different from the second arrangement of digitizers, with the first number of digitizers interleaved horizontally being different from the third number of digitizers interleaved horizontally or the second number of digitizers interleaved vertically being different from the fourth number of digitizers interleaved vertically;
• selecting, by the electronic test instrument, the first arrangement of digitizers from among the multiple different arrangements of the plurality of digitizers that result in valid configurations of the electronic test instrument;
• acquiring, by the electronic test instrument as a result of the electronic test instrument selecting the first arrangement of digitizers from among the multiple different arrangements of the plurality of digitizers, an electrical signal with the plurality of digitizers of the electronic test instrument being configured according to the first arrangement of digitizers;
• and
• presenting, by the electronic test instrument, a representation of the acquired electrical signal on the display of the electronic test instrument.
