2. Select a timebase between 50 ms to 25 µs. In this example, set to

100 µs.

3. Set MemDepth to Normal from the Horizon menu. Then press

, select Acquire menu and note the Sa Rate to be 12.50MSa.

4. Now, go back to Horizon menu and change MemDepth to Long

Mem. Go back to Acquire menu afterwards and note the Sa Rate is

now 100.0MSa.

5. The differences can be visually observed by pressing to stop

the waveform at 100 µs. Then adjust the horizontal scale factor to a

slower timebase until the entire waveform captured can be shown

on the display.

6. Observe with both MemDepth set to Normal and Long Mem.

7. Below is an example between the two captured at 100 µs timebase.

Figure 28 - Normal Memory Depth

Figure 29 - Long Memory Depth

Note: Different timebase settings will result in different sampling rates,

both with normal and long memory depth configured in MemDepth.

Selecting a timebase lower than 50 ms will automatically set the

instrument into scan mode. Deep memory is not supported in scan mode.

For timebase selections faster than 25 µs, the deep memory function will

have an adverse affect and will result in fewer sample points than if deep

memory is disabled.

Below is a table describing the different sampling rates for different

horizontal timebase settings with and without deep memory enabled.

The 2510 series digital storage oscilloscope comes with application software

which provides most of the controls that emulate the front panel of the

instrument. The miniUSB device port on the side of the instrument, when

not used for probe compensation, can be used to connect to a computer

using a miniUSB to USB type A cable and allow remote communication via

the software.

The software is free and can be downloaded at www.bkprecision.com

Remote communication is supported using the software only. Remote

commands are not available.

Frequency Asked Questions

Oscilloscope

1. I pressed the auto button, but it says no signal. Is it malfunctioning?

The auto function does not work for all waveforms. Usually,

waveforms that are periodic can be detected.

2. How do I adjust the trigger level?

The and keys are used to adjust trigger level.

However, if you select a menu option that has a symbol,

trigger level cannot be adjusted until you exit the menu or select a

different menu option that does not require the use of the same

keys as the trigger level adjust.

3. There is no Single button, how do I perform a single trigger capture?

Press to enter the Trigger menu, and set Mode to Single.

Then, use button to reset for each single capture.

4. How do I enter SCAN mode?

SCAN mode is available for timebase settings from 100 ms up to 50

s and is automatic. It is not available for timebase settings below

100 ms.

145

Multimeter

1. After I change a menu selection, how do I set the changes and close

the menu window?

Press the or keys to set the menu changes and to close

the menu window.

2. I cannot measure any current. Is there a problem?

There are 2 ports to measure current, one is labeled 10 A to

measure current up to 10 A. The other is labeled mA, which is

designed to only measure up to 600 mA. Both terminals have an

internal protection fuse. If you are not getting any measurements

from connecting to the correct port:

a. Check that there is current flowing from your DUT.

b. Your meter may not be in the correct range to make the

measurement. Change it to Auto range or change the range

manually to one suitable for the measurement.

c. Fuse may be blown for the 10 A input.
