:FUNCtion<m> Commands 20

Keysight InfiniiVision 4000 X-Series Oscilloscopes Programmer's Guide 469

:FUNCtion<m>:DISPlay

(see page 1610)

Command Syntax

:FUNCtion<m>:DISPlay <display>

<m> ::= 1 to (# math functions) in NR1 format

<display> ::= {{1 | ON} | {0 | OFF}}

The :FUNCtion<m>:DISPlay command turns the display of the function on or off.

When ON is selected, the function operates as specified by the other

:FUNCtion<m> commands.

One math function can be displayed at a time. If one math function is on and then

another math function is turned on, the first math function will be turned off.

When math functions are off, they are still calculated so that they can be

cascaded, that is, used as a source for a higher math function.

Query Syntax

:FUNCtion<m>:DISPlay?

The :FUNCtion<m>:DISPlay? query returns whether the function display is on or

off.

Return Format

<display> ::= {1 | 0}

• ":BLANk" on page 266

• ":STATus" on page 294

NOTE

Automatic vertical scaling of the math function waveform occurs when the function display is

turned from off to on. If you wait for the operation to complete (with an *OPC? query for

example), then query the math functions's scale, you can see the vertical scaling that was

automatically determined.
