TRACe Subsystem 3–178 AM700 Audio Measurement Set Programmer Manual The units of the returned data pairs depend on the measurement setup in the view . The possible choices are: Frequency , Level, THD, THD+N, IMD, Phase Diff, Separation, Crosstalk + Noise, and Level Dif ference versus either Frequency or Level. The default units for the traces fol[...]

TRACe Subsystem AM700 Audio Measurement Set Programmer Manual 3–179 TRACe:DATA <trace_name>,[X,Y]{,X,Y} Usage: TRAC:DA T A can be used to assign new values to the measurement trace and available reference traces. Previous trace values are discarded. For XY plots, the numbers that are assigned are XY pairs. Example: TRAC:DATA AME1_REF,10000,[...]

TRACe Subsystem 3–180 AM700 Audio Measurement Set Programmer Manual the Audio Analyzer traces and the multitone traces. The fft trace queries return the amplitude of the data, in dBu, in each bin only for each of the bins and the monitor traces return the amplitude of the data points. Y ou should always check the number of data points if you ever[...]

TRIGger Subsystem AM700 Audio Measurement Set Programmer Manual 3–181 TRiGger Subsystem The trigger subsystem in the AM700 contains commands only to start and stop a sweep. If a change to a list or sweep is made after a sweep is started, that sweep must either finish naturally or be terminated with STOP before the change is effected and a new swe[...]

UNIT Subsystem 3–182 AM700 Audio Measurement Set Programmer Manual UNIT Subsystem Default units are defined, where applicable, for each SCPI command. The UNIT subsystem provides a mechanism to change the default values. The units selected apply to the designated command parameters for both command and response, but NOT to the displayed units in t[...]

UNIT Subsystem AM700 Audio Measurement Set Programmer Manual 3–183 UNIT:IMPedance [Ohm|kOhm] Usage: Sets or queries the unit associated with an IMPedance query reply or command entry . Query: unit:imp? returns the current IMPedence unit setting as Ohm or kOhm. *RST: Sets the impedance unit to Ohm. UNIT:RATio [PCT|DB] Usage: Sets or queries the un[...]

UNIT Subsystem 3–184 AM700 Audio Measurement Set Programmer Manual dBv is a voltage ratio between the measured voltage and 1 V . dBFS is a voltage ratio between the measured voltage and the full scale voltage calibration factor CAL:VOLT:FS . It is primarily intended for digital levels. Query: UNIT:VOLT? returns the current unit setting associated[...]

AM700 Audio Measurement Set Programmer Manual 4–1 Examples The example given here is based on writing a function. Functions can be learned through the front panel, but they may also be written externally to the AM700 Audio Measurement Set loaded when needed. Functions are a list of SCPI (T cl) commends used to direct the measurements of the audio[...]

Examples 4–2 AM700 Audio Measurement Set Programmer Manual The T cl parser looks first to see if it is a T cl command that it knows about; if so, it runs it as a T cl command. If not, the parser looks for an *, a ?, or a : in the command lines to see if it is a SCPI command. Putting the letters “scpi” in front of the SCPI commands immediately[...]
