Using Status Registers A wide range of status registers allows the oscilloscope’s internal processing status to be determined quickly at any time. These registers and the instrument’s status reporting system are designed to comply with IEEE 488.2 recommendations. Following an overview, starting this page, each of the registers and their roles are described. Related functions are grouped together in common status registers.

WAVEFORM TRANSFER STORE_SETUP, STST Command /Query DESCRIPTION The STORE_SETUP command controls the way in which traces will be stored. A single trace or all displayed traces may be enabled for storage. COMMAND SYNTAX STore_SeTup [, ] : = {C1,C2,C3,C4,ALL_DISPLAYED } : ={M1~M10(or M20 in the CFL series),UDSK} QUERY SYNTAX STore_SeTup? RESPONSE FORMAT STore_SeTup , EXAMPLE The following command selects Channel 1 to be stored.

ACQUISITION SAMPLE_STATUS, SAST Query DESCRIPTION The SAST? query the acquisition status of the scope. QUERY SYNTAX SAST? RESPONSE FORMAT SAST < status > EXAMPLE The following command reads the acquisition status of the scope.
PAGE 105
ACQUISITION SAMPLE_RATE, SARA Query DESCRIPTION The SARA? query returns the sample rate of the scope. QUERY SYNTAX SARA? RESPONSE FORMAT SARA EXAMPLE The following command reads the sample rate of the scope. Command message: SARA? Response message: SARA 500.
PAGE 106
ACQUISITION SAMPLE_NUM, SANU Query DESCRIPTION The SANU? query returns the number of sampled points available from last acquisition and the trigger position. QUERY SYNTAX SANU? RESPONSE FORMAT SANU EXAMPLE The following command reads the number of sampled points available from last acquisition from the Channel 2.
PAGE 107
ACQUISITION SKEW, SKEW Command DESCRIPTION The SKEW command sets the skew value of the specified trace. The response to the SKEW? query indicates the skew value of the specified trace. COMMAND SYNTAX :SKEW : = {C1,C2,C3,C4 } : = it is a value about time.
PAGE 108
FUNCTION SET50, SET50 Command DESCRIPTION The SET50 command sets the trigger level of the specified trigger source to the centre of the signal amplitude.
PAGE 109
ACQUISITION SINXX_SAMPLE, SXSA Command /Query DESCRIPTION The SINXX_SAMPLE command sets the way of interpolation. The response to the SINXX_SAMPLE? query indicates the way of interpolation.
PAGE 110
ACQUISITION TIME_DIV, TDIV Command /Query DESCRIPTION The TIME_DIV command modifies the timebase setting. The new timebase setting may be specified with suffixes: NS for nanoseconds, US for microseconds, MS for milliseconds, S for seconds, or KS for kiloseconds. An out-ofrange value causes the VAB bit (bit 2) in the STB register to be set. The TIME_DIV? query returns the current timebase setting. COMMAND SYNTAX Time_DIV :={1NS(not every type has this value),2.
PAGE 111
WAVEFORM TRANSFER TEMPLATE, TMPL Query DESCRIPTION The TEMPLATE? query produces a copy of the template that describes the various logical entities making up a complete waveform. In particular, the template describes in full detail the variables contained in the descriptor part of a waveform. QUERY SYNTAX TeMPLate? RESPONSE FORMAT TeMPLate “
