General Information Supplemental Characteristics Marker Functions Time Interval The X and O markers measure the time interval between a point on a timing waveform and the trigger, two points on the same timing waveform, two points on different waveforms, or two states (time tagging on). Delta States (state analyzer only) The X and O markers measure the number of tagged states between one state and trigger or between two states. Patterns The X and O markers can be used to locate the nth occurrenc

Preparing For Use This chapter gives you instructions for preparing the logic analyzer for use. Power Requirements The logic analyzer requires a power source of either 115 Vac or 230 Vac, –22 % to +10 %, single phase, 48 to 66 Hz, 200 Watts maximum power. Operating Environment The operating environment is listed in chapter 1. Note the noncondensing humidity limitation. Condensation within the instrument can cause poor operation or malfunction. Provide protection against internal condensation

Preparing for Use Ferrites Ferrites Ferrites are included in the 1664A accessory pouch for the logic analyzer cable. When properly installed, the ferrites reduce RFI emissions from the logic analyzer. In order to ensure compliance of the 1664A Logic Analyzer to the CISPR11 Class A radio frequency interference (RFI) limits, you must install the ferrite to absorb radio frequency energy. Note: Adding or removing the ferrite will not affect the normal operation of the analyzer. Ferrite Installatio

Preparing for Use To apply power To apply power Electrostatic discharge can damage electronic components. Use grounded wriststraps and CAUTION mats when performing any service to the logic analyzer. 1 Check that the line voltage selector, located on the rear panel, is on the correct setting and the correct fuse is installed. See also, "To set the line voltage" on this page. 2 Connect the power cord to the instrument and to the power source. This instrument is equipped with a three-wire power ca
