MEMory:END
Function Sets the data to transmit or queries the current
setting.
Syntax :MEMory:END <NRf>
:MEMory:END?
During time stamp mode, <NRf>=Number of
points(1 to 512,000)
During hardware histogram mode,
<Time>= -3.5 ns to 3.2 ms (in 25 ps
steps)
Example :MEMORY:END 1ns
:MEMORY:END?
→
:MEMORY:END 1.000E-09
MEMory:FORMat
Function Sets the format of the transmission data or
queries the current setting.
Syntax :MEMory:FORMat {ASCii|BINary}
:MEMory:FORMat?
Example :MEMORY:FORMAT ASCII
:MEMORY:FORMAT?
→
:MEMORY:FORMAT ASCII
MEMory:SEND?
Function Queries (transmits) the measured data
specified with the "MEMory:DATaselect"
command.
Syntax :MEMory:SEND?
Example :MEMORY:SEND?
→
#800000016abcdabceabcfabcg
Description • When the transmission format is ASCII, the
response data in <NR3> format are output
the number of times equal to the number of
data points separated by commas ( , ). When
the format is BINARY, a single block of data
is output.
• The conversion equation from the binary data
to the real number is as follows:
For hardware histogram mode
Frequency (FREQuency):
Stored as an unsigned four-byte integer
Measured data (MEASuredata):
Consider it an unsigned four-byte integer.
The measured value is this number multiplied
by 25 ps.
3.11 MEMory Group/3.12 RECall Group
For time stamp mode
Frequency (FREQuency):
Frequency cannot be output directly in the
time stamp mode.
Measured data (MEASuredata):
Consider it an unsigned four-byte integer.
The measured value is this number multiplied
by 25 ps.
Time stamp value (TSTamp):
Consider it an unsigned four-byte integer.
The time stamp value is this number
multiplied the following times.
When the sampling interval is 0 (MINimum)

MEMory:SIZE?
Function Queries the number of measured data points.
Syntax :MEMory:SIZE?
Example :MEMORY:SIZE?
→
10000
Description [ NAN ] is returned when the sampling mode is set
to hardware histogram.
MEMory:STARt
Function Sets the data position of the start of the
transmission or queries the current setting.
Syntax :MEMory:STARt <NRf>
:MEMory:STARt?
During time stamp mode, <NRf>=Number of
points(1 to 512,000)
During hardware histogram mode,
<Time>= -3.5 ns to 3.2

:RECall <Space> <NRf>
RECall
Function Recalls the setup information.
Syntax RECall <NRf>
<NRf>=0 to 9
