*SRE? might return 32, showing that the bits in the SRER have the binary value
of 00100000.
*STB? (Query Only)

TEKSecure (No Query Form)
This command initializes both waveform and setup memories, overwriting any
previously stored data. These are the WFMInpre?, WFMOutpre?,andDATa
command values after the
TEKSecure operation.

Syntax
TEKSecure
Examples
TEKSECURE initializes both waveform and setup memories.
This is a program example of how to generate an SRQ when
TEKSECURE
completes:
# Bit 0 of t he DESE (Device Event Status Enable Reg ister)
# enables OPC to be repo rted to t he SESR (Standard Event
# Status Register)
DESE 255
# Bit 0 of t he ESER (Event Status Enable Register)
# enables OPC to be summ arized in the ESB (Event St atus #
Bit) of the SBR (Status Byte Register)
*ESE 255
# Bit 5 of t he SRE ( Service Request Enable Register)
enables
# the generation of SRQ when the ESB bit of the SBR
becomes # TRUE
*SRE 32
TEKSECURE;*OPC
When the TEKSECURE operation has completed, the OPC bit of the SESR will be
TRUE and SRQ will have been generated.

Arguments
<QString> is a t
ime in the form "hh:mm:ss" where hh refers to a two-digit hour
number, mm refers to a two-digit minute number from 00 to 59, and ss refers to a
two-digit second number from 00 to 59.
Examples
TIME "14:00:00" sets the time to exactly 2:00 p.m.
TIME? might return :TIME "14:05:17” indicating the current time is set to 2:05
p.m. and 17 seconds.
TOTaluptime? (Query Only)
This query returns the total number of hours that the oscilloscope has been
powered on since the nonvolatile memory was last programmed (usually sincethe
initial manufacturing process).
