Agilent Technologies 35670A User Manual

Adjusting the units / scale division You can adjust the units/scale division by using the
[
Y PER DIV (DECADES)
] softkey. For linear Y-axis, this specifies the number of units
per vertical scale division. For a log Y-axis, this specifies the number of decades
displayed.
When you select a new scale spacing, the currently active reference (top reference,
center reference, or bottom reference) is held the same and the rest of the scale
adjusted around this level. By the way, the reference softkey with a box around it is
the currently-active reference.
Matching X and Y scales You can use the [
MATCH X SCALE
] softkey to set the X-axis
scale of the inactive trace to the active trace. The [
MATCH Y SCALE
] softkey is similar,
but sets the Y-axis scales to the same scaling.
This lets you easily set both traces to identical X-axis or Y-axis scales. This makes it
easier to compare data on both traces, particularly when you have the upper/lower or
front/back display formats selected.
Axes scale markers The Agilent 35670A offers a feature called axes scaling. This lets
you expand the displayed trace to examine it more closely. Using the axes scale
markers, you can:
• Specify X-axis or Y-axis scaling.
• Move markers using the knob or numeric entry keys.
• Return to a full-span display.
• Expand the band identified by the markers to fill the display.
• Specify which of the markers should hold its position and which should move.
It is important to remember that axes scaling only expands the displayed
data—it does not give you better measurement resolution. If you need more
resolution to interpret a measurement, either increase the display resolution or
reduce the analyzer’s frequency span—then make another measurement.
To learn more about the axes scale markers, see online help.
Measure the device-under-test / signal source
To begin a measurement press the [
Start
]key. [
Start
]clears all measurement
data from the analyzer’s buffers.
The [
Pause-Cont
] key stops the analyzer in the middle of a measurement. The
analyzer displays the measurement as completed so far. Press [
Pause-Cont
]
once more to continue the measurement—the analyzer begins where it left off.
[
Pause-Cont
] does not clear the analyzer’s buffers.
