During peak detection the oscilloscope distinguishes bet ween two types Acquisition peak detection Each A D converter converts at the full sampling rate no Interlace mode even if results have not been written to the acquisition memory at full sampling rate for slow time bases for instance If peak detection is activated unused converter values will be evaluated to detect minimum and maximum amplitudes During this process the identified minimum and maximum values including sampling Interval are written to the acquisition memory As a result the acquisition memory stores data pairs representing the signal sequence according to the sampling interval The smallest detectable pulse is the period of the maximum sampling rate no Interlace mode This describes the so called acquisition peak detection Memory peak detection A hardware peak detection Is not available if data is written to the acquisition memory at the ADC s maximum sample rate For slow time bases and the record mode is set to AUTOMATIC or MA WFM RATE not all data from the acquisition memory will display on the screen With peak detection activated when reading out skipped data will be used to create a minimum and maximum value The smallest detectable pulse is the period of the sample rate used to write to the acquisition memory This describes the so called memory peak detection If one of the peak detection modes or a combination of the two are used the corr

19. 2 USB TMC A modern alternative to the virtual COM port VCP is the control via USB TMC class TMC stands for lest amp Measurement Class which indicates that the connec ted measurement instrument can be recognized without special Windows drivers if VISA drivers are installed and that it can be used directly in corresponding environments The GPIB interface serves as model to the structure of the TMC design A major benefit of the USB TMC class is that by sampling specific registers the user can determine if commands have been terminated and if they have been processed correctly However the communication via VCP requires analysis and polling mechanisms within the cont rolling software which may significantly strain the interface of the measurement instruments The TMC status registers solve this problem with the USB TMC in the same manner as is the case with the GPIB interface for the hardware namely via corresponding control lines 14 2 1 USB TMC Configuration The R S HMO1002 require a generic USB instrument driver to be operated in USB TMC mode The USB Test amp Measurement class USB TMC is a protocol that enables GPIB like communication via USB interfaces and a sepa rate instrument class of the USB specification The USB TMC protocol supports service requests trigger and other GPIB specific commands The driver is included in the NI VISA package Virtual Instrument Software Architecture and can be downloaded at http
