## Query Syntax

    :CHANnelN:YTOP?

Where N identifies a specific channel in the form "<connection1-8>_<ch1-8>". With connection 1, the connection number part (that is, "1_") is optional, and you can simply use the channel number "<ch1-8>". For example, connection 4 channel 2 is `CHANnel4_2`.

## Description

Queries the amplitude value represented by the graticule's top edge. You cannot set the value with this query. To query the amplitude value represented by the graticule's bottom edge, use `:CHANnel:YBOTtom?`. Use the `:CHANnel:YSCale` command to set the amplitude scale (volts or Watts). Use the `:CHANnel:YOFFset` command to set the amplitude offset.
