CURSor:VBArs

:VDELTa? (Query Only)

Returns the vertical (amplitude) difference between the two vertical bar cursors.

Theunitsarespeciﬁed by the CURSor:HBArs:UNits query.

Conditions

This command applies to the TDS1000B, TDS2000B, TDS2000C, and TPS2000

Series only.

Syntax

CURSor:VBArs:VDELTa?

Returns

<NR3> indicates the vertical difference between the two vertical bar cursors.

Examples

CURSOR:VBARS:VDELTA? might return 1.064E+0, indicating that the vertical

difference between the vertical bar cursor ticks is 1.064 units.

CURVe

Transfers oscilloscope waveform data to and from the oscilloscope in binary or

ASCII format. Each waveform tha t is transferred has an associated waveform

preamble that contains information such as data format a nd scale. For information

about the waveform preamble, refer to WFMPre?. The data format is speciﬁed

by the DATa:ENCdg and DATa:WIDth commands.

The CURVe? query sends data from the oscilloscope to an external device. The

data source is speciﬁed by the DATa:SOUrce command. The ﬁrst and last data

points that are transferred are speciﬁed by the DATa:STARt and DATa:STOP

commands.

NOTE. If the waveform speciﬁed by the DATa:SOUrce command is not displayed,

the CURVe? query returns nothing, and generates events 2244 (Waveform

requested is not activated) and 420 (Query UNTERMINATED).

In Scan Mode (Sec/div ≥100 ms and AUTO Mode), approximately one division

of data points will be invalid due to the blanked moving cursor.

The CURVe set command sends waveform data from an e xternal device to the

oscilloscope. The data is stored in the stored waveform location speciﬁed by

DATa:DESTination, starting with the data point speciﬁed by DATa:STARt. Only

one waveform can be transferred at a time. The waveform will only be displayed

if the reference waveform is displayed.
