Examples
MEASUREMENT:M
EAS2:SOURCE1:EDGE:DIRECTION FORWARD
causes the
instrument to search forward from the beginning of the Source 1 waveform (or
the beginning of the gated region, if gates are enabled) for the first specified edge
(rising or falling).
MEASUREMENT:MEAS8:SOURCE1 :EDGE:DIRECTION? might return
MEASUREMENT:MEAS8:SOURCE1 :EDGE:DIRECTION FORWARD, indicating that
the instrument will search forward from the beginning of the Source 1 waveform
(or the beginning of the gated region, if gates are enabled) for the specified edge
(rising or
falling) when taking Measurement 8 .
MEASUrement:MEAS<x>:SOUrce<x>:EDGE:SLOPe
This command sets or queries the slope (or polarity) of the edges used in delay
time measurements. The measurement slot is specified by x, which can be 1
through 8; the source is specified by x, which can be 1 (source waveform) or
2 (destination waveform). For edge measurements other than delay, the slope
is dete
rmined implicitly (for example, rise time measurements use positive
slopes). If gates are enabled (see the MEASUrement:MEAS<x>:GATing:STATE
command), the instrument finds the edge within the measurement zone; o therwise,
the instrument finds the edge within the entire waveform record.
Sending this command is equivalent to selecting an option button (±, +, or -) for
Slope in the Edges section of the Region dialog in the Measurement Setup dialog
box. (A delay measurement must be selected before these buttons are active.)
Use the MEASUrement:MEAS<x>:SOURCE:EDGE:DIRection command to
set the direction that the instrument uses to look for the rising or falling edge
of the waveforms.
NO
TE. The SOURCE<x> SOURCE:<<x> argument specifies the
source, which can be source 1 or source 2. To set the actual waveform
(channel, reference, or math) that is assigned to source, you must use the
MEASUrement:MEAS<x>:SOURCE<x> WFM command. Two sources are
provided because some measurements (gain, phase) require two sources.
