If the selected source channel is not used in oscilloscope triggering, press
Auto
Range
to disable or enable automatic adjustment of the DVM channel's vertical
scale, vertical (ground level) position, and trigger (threshold voltage) level (used
for the counter frequency measurement).
When enabled,
Auto Range
overrides attempted adjustments of the channel's
vertical scale and position knobs.
When disabled, you can use the channel's vertical scale and position knobs
normally.
Counter
The counter analysis feature provides frequency, period, or edge event (totalize)
counter measurements on any analog channel.
The counter counts trigger level crossings within a certain amount of time (gate
time) and displays the results on a seven-segment readout (like you would see on
a standalone counter instrument).
For frequency and period counter measurements:
• The gate time is specified indirectly by the selected number of digits of
resolution, from 3 to 8. For higher resolutions, the gate time is greater.
• Up to 1 GHz (1.2 GHz typical) frequencies can be measured. With 8 digits of
resolution, the counter will saturate for signals greater than 470 MHz.
For totalize measurements:
• A running count of edges is kept. You can choose whether to count positive or
negative edges, and when edge triggering on any analog channel, you can gate
the count with a positive or negative pulse on a second analog channel.
• Edge events with up to 1 GHz (1.2 GHz typical) frequencies can be counted.
• When gating the count, the gating signal setup time is 0 ns typical and the hold
time is 3.5 ns typical when using similar probes for the totalize source and the
gate source.
The counter is asynchronous from the oscilloscope's acquisition system and is
always acquiring.
To use the counter:
