DS4000E Programming Guide
Remarks
The upper limit, middle value, and lower limit of the threshold are expressed as the percentages of the
vertical amplitude. Setting the threshold will affect the measurement results of the time, delay and
phase parameters.
The <max> value must be at least 1 greater than the <mid> value. When the specified <max> value
is smaller than or equal to the current <mid> value, the <mid> value (even the <min> value) will be
automatically decreased so as to keep itself smaller than the <max> value.
The <min> value must be at least 1 smaller than the <mid> value. When the specified <min> value is
greater than or equal to the current <mid> value, the <mid> value (even the <max> value) will be
automatically increased so as to keep itself greater than the <min> value.
The actual range of the <mid> value is related to the current <max> and <min> values. It ranges
from (the current <min> value plus 1) to (the current <max> value minus 1).
Return Format
The query returns an integer.

:MEASure:SETup:PSB
Syntax
:MEASure:SETup:PSA <sourA>
:MEASure:SETup:PSA?
:MEASure:SETup:PSB <sourB>
:MEASure:SETup:PSB?
Description
Sets or queries Source A and Source B of phase measurement.

Remarks
The phase measurement function is used to measure the following four kinds of phase deviations between
the specified channels:
Source A rising edge-Source B rising edge (refer to the :MEASure:RPHase command)
Source A rising edge-Source B falling edge (refer to the :MEASure:R2FPhase command)
Source A falling edge-Source B falling edge (refer to the :MEASure:FPHase command)
Source A falling edge-Source B rising edge (refer to the :MEASure:F2RPhase command)
Return Format
The query returns CHAN1, CHAN2, CHAN3, or CHAN4.
