Vertical OFST
Command/Query
DESCRIPTION The OFST command sets the vertical position (offset)
of the specified input channel.
The setting range depends on the vertical sensitivity.
The OFST? query returns the defined vertical position
(offset).
Both command and query are always available regardless
if the specified channel's trace is on or off.
Probe ratio is considered in the vertical position
(offset) value to set or query.
COMMAND SYNTAX <trace>:OFST <offset>
<trace>: = {C1, C2, C3, C4, M1} (WJ354/334/324/314)
: = {C1, C2, M1} (WJ352/332/322/312)
<offset>:= Offset voltage. The <DECIMAL NUMERIC
PROGRAM DATA> format is basically used in <offset>, and
the suffix is also valid. For the setting range and
rounding rule, see "Remarks".
QUERY SYNTAX <trace>:OFST?
RESPONSE FORMAT <offset>
The current offset is identified in <offset> in <NR3
Numeric Response Data> format.
REMARKS
Setting range of OFST command. (when probe ratio is 1:1)
Trace Vertical sensitivity Offsetting range
2mV/div ∼ 50mV/div ±1 V
100mV/div ∼ 500mV/div ±10 V C1,C2,C3,C4
1V/div ∼ 10V/div ±100 V
M1 (+, -, X) ±500 div
M1 (FFT) -100～+150 dBm
Any value outside the above range is rounded to the maximum or minimum
permissible value, whichever is nearest. In addition, some value may be rounded
to a permissible smaller value.
When the probe ratio is 10:1, 20:1, 100:1, 200:1, 1000:1or 2000:1, the above
range is multiplied by 10, 100, 1000 or 2000.
When the probe ratio is set to "AUTO", the above range is multiplied by 1, 10,
or 100, depending on the detected probe ratio.
