Setting Channels And Traces; Setting Upper Limits Of Number Of Channels/Traces - Agilent Technologies ENA Series User Manual

Setting Channels and Traces

The E5070B/E5071B allows you to use up to 16 channels (when the number of traces is up
to 4) to perform measurement under 16 different stimulus conditions.
For each channel, up to 16 traces (measurement parameters) can be displayed (when the
number of channels is up to 4). Because multiple traces can be displayed for each channel,
no feature is provided to link the stimulus conditions between channels, and each channel
is always independent of the others. In other words, for the E5070B/E5071B, you need to
set the measurement conditions and execute calibration for each channel you use for
measurement.
With the E5070B/E5071B, you can change the number of available channels and the upper
limit of the number of traces. If you change the upper limit setting, you need to restart the
firmware of the E5070B/E5071B. Therefore, first, set the upper limit appropriately
depending on the numbers of channels and traces necessary for your measurement.
When you set items whose setting target is channels/traces (refer to "Parameter setting for
each setup item (analyzer, channel, trace)" on page 67), the target is the selected (active)
channel/trace. You can specify only the displayed channels/traces as active channels/traces.
Therefore, set the display of channels/traces before setting the measurement conditions.

Setting upper limits of number of channels/traces

You can select the upper limits of the number of channels and the number of traces from
the following combinations.
• 1 channels and 4 traces
• 2 channels and 4 traces
• 4 channels and 16 traces
• 9 channels and 9 traces
• 12 channels and 6 traces
• 16 channels and 4 traces
You may want to select the "1-channel, 4-trace" or "2-channel, 4-trace" configuration to
save the time required to save/call the instrument state file, since this takes longer with
other configurations.
NOTE
It's important to realize that the combination used to save a state file must be the same used
to recall it; that is, you cannot save a state file with one combination of channels/traces and
recall it with another combination. For more details, see "Saving and Recalling Instrument
State" on page 352.
NOTE When more than 1601 measurement points is set for 1 channel and 4 traces, the
E5070B/E5071B VBA macro function may not operate.
The selection procedure is as follows:
Step 1. Press
Step 2. Press
Step 3. Press
Step 4. Press the desired softkey to select the upper limits of the number of channels and the
number of traces.
