TPRM
Command/Query
The TPRM command sets the measurement conditions for
the automatic measurement item DELTAT set using the
MSEL command.
The TPRM? query returns the measurement conditions for
the automatic measurement item DELTAT set using the
MSEL command.
TPRM <from ch>, <from level>, <from edge>, <to ch>, <to
level>, <to edge>
<from ch>:={OFF, CH1, CH2, CH3, CH4, MATH}
(WJ354/334/324/314)
:={OFF, CH1, CH2, MATH}
(WJ352/332/322/312)
<from edge>:= {RISE, FALL}
<from level> is set in <DECIMAL NUMERIC PROGRAM DATA>
format. A voltage value in a range of –5 div to +5 div
from the center of the screen is set, assuming that the
ground level is 0 V.
<to ch>:={CH1, CH2, CH3, CH4, MATH}
(WJ354/334/324/314)
:={CH1, CH2, MATH} (WJ352/332/322/312)
<to edge>:= {RISE, FALL}
<to level> is set in <DECIMAL NUMERIC PROGRAM DATA>
format. A voltage value in a range of –5 div to +5 div
from the center of the screen is set, assuming that the
ground level is 0 V.
TPRM?
<from ch>, <from level>, <from edge>, <to ch>, <to
level>, <to edge>
<from level> shows a voltage value in a range of –5 div
to +5 div set in <NR3 Numeric Response Data> format,
assuming that the ground level is 0 V.
<to level> shows a voltage value in a range of –5 div
to +5 div set in <NR3 Numeric Response Data> format,
assuming that the ground level is 0 V.
If <from ch> is OFF, <from level> is returned as <from
ch> is CH1.
If <from ch> or <to ch> is MATH and the MATH is FFT,
<from level> or <to level> becomes +9.91000E+37 that
shows it is invalid.
If <from ch> or <to ch> is set to CH3 or CH4 in models
WJ352/332/322/312, it is rounded to CH1.
TPRM command reports device-specific error (DDE) when
MSEL is not DELTAT.
