HP 8753E manual Key Definitions

Power meter calibration occurs on each sweep. Each measurement point is measured by the power meter, which provides the analyzer with the actual power reading. The analyzer corrects the power level at that point. The number

of measurement/correction iterations performed on each poht is determined by the ~~~~~~~~~ softkey.

This measurement mode sweeps slowly, especially when the measured power is low. Low power levels require more time for the power meter to settle. The power meter correction table in memory is updated after each sweep. This table can be read or changed via HP-IB.

displays a table of limit segments on the LCD, superimposed on the trace. The edit limits menu is presented so that limits can be delIned or changed. It is not necessary for limit lines or limit testing to be on while limits are defined.

presents the edit list menu. This is used in conjtmction with the edit subsweep menu to define or modify the frequency

adjusts the electrical delay to balance the phase of the DUT. It simulates a variable length lossless transmission line, which can be added to or removed from a receiver input to compensate for interconnecting cables, etc This function is similar to

the mechanical or analog “line stretchers” of other network analyzers. Delay is annotated in units of time with secondary labeling in distance for the current velocity factor.

causes the instrument to beep once.

terminates the HP-GL “LB” command.

sets the lTL output on the test set interconnect to normally high with a 10 ps pulse high at the end of each sweep.

sets the lTL output on the test set interconnect to normally low with a 10 ps pulse low at the end of each sweep.

deletes the entire title.

runs the selected service test.

selects the auto external source mode.

selects the manual external source mode.

is similar to the trigger on sweep, but triggers each data point in a sweep.

is used when the sweep is triggered on an externally generated signal COMeCted to the rear panel EXT TRIGGER input. External trigger mode is allowed in every sweep mode.
