Anritsu ML2430A operation manual Profile Operation Mode, Typical Setup

PROCEDURES PROFILE OPERATION MODE

NOTE

To operate the Univer- sal power sensors in profile mode Option 1 must be fitted. Activate option 1 mode before selecting profile mode under the SENSOR Setup OPTION FAST CW menu.

NOTE

Dynamic range is lim- ited in Profile mode to DC ranges only. For maximum dynamic range, measured sig- nals need to be repeti- tive (not single-shot) when profiling over less than 30ms width. Above this, single-shot profiles can be mea- sured over the full dy- namic range.

TYPICAL SETUP

To view the time profile of a signal, enter the PROFILE mode via SYSTEMSETUPMODE (toggles through READOUT, PROFILE and POWER vs. TIME ). Parameters needed to set up a PROFILE display are:

1.TRIGGERSETUP provides access to a special TRIGGER configura- tion options. The default mode is CONTINUOUS which provides for a non-synchronized, oscilloscope type display. This type of display is useful for general monitoring of a signal and showing its variation over time. The settings for the DELAY and gate WIDTH provide the points at which the measurement is triggered and read out of the cursor. The other options are similar to other triggering modes.

2.SYSTEMPROFILE sets up the channel (1 or 2 ) to be displayed and the time-axis, as well as the way that the data is displayed (for exam- ple, monitoring the minimum or maximum data over time). Note that in all cases, the PROFILECHANNEL selection (1 or 2 ) relates to a measurement channel set up in the CHANNEL menu, not directly to the A or B sensors.

NOTE

If the DATA HOLD mode is set to display min or max data, as opposed to the default (NORMAL), the display will continue to track the min/max until the DATA HOLD mode is returned to NORMAL.

3.SYSTEMCONTROL provides control over the readout and CURSORs as well as the scaling of the display. From the CURSOR menu (using the << and >> arrows) the positions of the readout cursors can be ad- justed. The cursors directly relate to the DELAY and gate WIDTH pa- rameters in the TRIGGERSETUP menu, but allow for visual move- ment of the parameters on the display itself. The TRIGGERSETUP menu requires direct entry of the actual parameters when the timing criteria is known.

A typical situation with no triggering (CONTINUOUS):

1.Select SYSTEMSETUPPRESET to reset the instrument to the standard de- fault conditions (see Appendix A, Section A-3 for a listing of the system defaults).

2.Connect sensor A to the signal source.

3.Select SYSTEMSETUP and press MODE to select PROFILE.

4.Press CLR or any other menu key to return to the display screen. The display now shows a power profile of sensor A on channel 1.

5.Press SYSTEMCONTROL to get access to the cursor. Press << and >> to move the selected cursor, and SWAP to select the other cursor.
