TRACe:INDEX
Description: Set or return the array index for the first trace point to be returned next time the TRACe:DATA?
query is issued. Index 0 is the start of the trace buffer, and corresponds to the leftmost pixel on the
graph display. Index 500 is the last point, and is the rightmost pixel. Each time a block of data is
read, INDEX is automatically incremented by the COUNT value, so the full array can be split up
into blocks of manageable size and read with successive TRACe:DATA? queries. INDEX must
be reset to zero for each new trace that is to be dumped, whether or not all the points have been
read.
Syntax: TRACe[1|2|3|4|5|6|7]:INDEX <n>
Argument: <n> = 0 to 500
Valid Modes: All
TRACe:MAXimum:DATA?
Description: Return a comma-delimited array of power or voltage maximum values corresponding to all or a
portion of the graph mode display trace for the selected channel. Note that graph mode does not
have to be active to read the trace, and the maximum values are returned without regard to display
vertical scale and center settings. The array will consist of COUNT trace pixel maximum values,
beginning at pixel number INDEX, up to the last pixel of the trace (index = 500), and will be
returned in channel units. Maximum data is not available from the Math Channel (CHM). The
selected channel must be ―ON‖ to return measurement data.
Syntax: TRACe[1|2|3|4|6|7]:MAXimum:DATA?
Returns: PMAX(index), PMAX(index+1), PMAX(index+2).... PMAX(index+count) or
VMAX(index), VMAX(index+1), VMAX(index+2).... VMAX(index+count)
Valid Modes: Modulated and Pulse.
TRACe:MINimum:DATA?
Description: Return a comma-delimited array of power or voltage minimum values corresponding to all or a
portion of the graph mode display trace for the selected channel. Note that graph mode does not
have to be active to read the trace, and the minimum values are returned without regard to display
vertical scale and center settings. The array will consist of COUNT trace pixel minimum values,
beginning at pixel number INDEX, up to the last pixel of the trace (index = 500), and will be
returned in channel units. Minimum data is not available from the Math Channel (CHM). The
selected channel must be ―ON‖ to return measurement data.
Syntax: TRACe[1|2|3|4|6|7]:MINimum:DATA?
Returns: PMIN(index), PMIN(index+1), PMIN(index+2).... PMIN(index+count) or
VMIN(index), VMIN(index+1), VMIN(index+2).... VMIN(index+count)
Valid Modes: Modulated and Pulse.
