Significant differences to the 7B53A include:
Significant differences to the 7B53A include:
* slowest sweep speed 50ms/div
* slowest sweep speed 50 ms/div
* no x10 magnifier, direct access to 5ns/div speed
* no ×10 magnifier, direct access to 5 ns/div speed
* timebase B always runs after timebase A and has no separate trigger
* timebase B always runs after timebase A and has no separate trigger
* timebase mode A+B actually displays 'A intensified by B' alternating with B
* timebase mode A+B actually displays 'A intensified by B' alternating with B
