The Power-Up Routine When power is applied to the HP 16500B Logic Analysis System mainframe, a seriesof tasks called the power-up routine is performed to initialize and to verify operationof the mainframe. The mainframe monitor reports the progress and status of thepower-up routine. Each of the task...

The System Configuration Menu When the power-up routine is complete and the HP 16500B is operational, the SystemConfiguration menu is displayed. The names of the installed modules appear in fields on theleft side of the display. The fields correspond to the slot into which the module is installed. U...

Self-Tests Description The self-tests identify the correct operation of the major sub-systems in theHP 16500B Logic Analysis System mainframe. The self-tests are not intended forcomponent-level diagnostics. Two types of tests are performed on the HP 16500B mainframe: the power-upself-tests and the f...

Correlator Test The correlator test verifies that the intermodule bus time correlator on the microprocessorboard is functioning properly. If the correlator is functioning, then intermodulemeasurements can be time-correlated to within 2 ns. This test reports either a pass or failmessage. For Correlat...

RAM Test This test checks the mainframe RAM on the microprocessor board. The test performs anon-destructive pattern write/read at every location. The initial RAM contents are restoredafter the test. For RAM Test failures, first you can suspect a faulty SIMM module, then youcan suspect a faulty micro...

Page 126 - Intermodule Test

Possible problems causing a failed message in either the flexible disk drive or hard disk driveinclude the following: • A damaged or disconnected disk drive cable. • Wrong disk formatting or no disk formatting. • The disk write-protect tab set to the write-protect position. • A faulty disk drive. • ...

RS-232C The logic analysis system interfaces with RS-232C communication lines through astandard 25 pin D connector. The logic analysis system is compatible with RS-232Cprotocol. When a hardwire handshake method is used, the Data Terminal Ready(DTR) line, pin 20 on the connector, is used to signal if...
