Mask Testing File format for masks: MSK MSK is the specific binary format for masks of the R&S RTB2000. It contains pairs of amplitude values (in divisions) , their sample indexes and current instrument settings. Thus, the amplitude values are not related to time and voltage.

Page 482: C Status Reporting System
® Status Reporting System R&S RTB2000 Structure of a SCPI Status Register C Status Reporting System The status reporting system stores all information on the current operating state of the instrument, and on errors which have occurred. This information is stored in the status registers and in the error queue.
Page 483: Hierarchy Of Status Registers
® Status Reporting System R&S RTB2000 Hierarchy of status registers – PTR bit =1: the EVENt bit is set. – PTR bit =0: the EVENt bit is not set. This part can be written into and read as required. Its contents are not affected by reading.
Page 484 ® Status Reporting System R&S RTB2000 Hierarchy of status registers Figure C-2: Overview of the status registers hierarchy ● STB, SRE The STatus Byte (STB) register and its associated mask register Service Request Enable (SRE) form the highest level of the status reporting system. The STB pro- vides a rough overview of the instrument status, collecting the information of the lower-level registers.
Page 485: Contents Of The Status Registers
® Status Reporting System R&S RTB2000 Contents of the Status Registers The output buffer contains the messages the instrument returns to the controller. It is not part of the status reporting system but determines the value of the MAV bit in the STB and thus is represented in the overview.
