That is sure the case.
BTW, a 7B53A is not the correct PI as a sweep. It is a sweep for something
like a 7603 or other 100 MHz mainframes.
The only problem with the 7B53A or other 100 MHz 7B5x timebases is
that the 7854 vertical delay line at 65ns is too short to show the
leading edge. The same restriction applies to the other 400 MHz and
faster mainframes. I am not sure about the 200 MHz mainframes which
have a 90ns delay line.
One might want to use the 7B53A for its delayed sweep, mixed sweep,
variable holdoff, or external amplifier in capability but in general
like you say, the 7B92A is a better choice.
The 7854 is a 400 MHz mainframe. The proper sweeps for the 7854 are the
7B80 & 7B85 or the 7B92A.
To use the digitizing functions properly, you need the 7B87.
The 7854 only requires the 7B87 for pretrigger and single shot
acquisitions. Full bandwidth equivalent time sampling acquisitions
work fine with any of the other timebases.
