Agilent MSO6014A Mixed Signal Oscilloscope
The 6014A is a combination oscilloscope and logic analyzer. The digital section on the
front panel is the logic analyzer part of the unit. The analog section on the front panel is the
oscilloscope part of the unit. The oscilloscope section is labeled analog and refers to the type of
input signal. The oscilloscope has a band width of 100 MHz and a maximum sampling speed of
2 G Sa/s ( 2 Giga samples/second or a sampling frequency of 2 GHz).
The introduction part of the Digitizing Oscilloscopes and the Logic Analyzers in the
Equipment Manual should be reviewed for basic theory operation. The controls for the 6014A
are similar to the HP 54601 oscilloscope and HP 54620A logic analyzer. Refer to these sections
in the Equipment Manual for an explanation of the operation and the controls. This section is a
supplement to the previous sections mentioned.
This unit, along with other scopes and analyzers, should be reset to factory default settings
before using. Press the Save/Recall button and then the Default Setup button to reset. This unit,
along with other scopes and analyzers, has an Auto-Scale button. Auto-Scale automatically
configures the scope to display the signals at its inputs. Students that use this function will not
learn the basic controls and how to display signals. The auto scale function can be misleading
when displaying a signal. In order to learn the operation of equipment, avoid the Auto-Scale
button. These units also do automatic measurements. Manual cursor measurements are more
accurate then automatic measurements. Use the cursor measurements for accurate measurements
and as a learning tool. Measurements should be taken at the center of the trace width.
This scope will recognize the 10:1 probes and adjust the probe setting.
BW Limit is located in the analog channel menu. This limits the bandwidth of the scope
to 20 MHz. This is used to filter out high frequency noise, provided the signal is composed of
low frequency components. This is a very low bandwidth and will distort waveforms, made up of
frequencies components above 20 MHz. It is best to leave BW Limit off in most situations.
Analog channel menu > probe > skew. Skew is used to remove delays in probe cables
between any two channels. This can occur with time intervals in the nS range. Attach both
probes to the same point and adjust the skew between channels.
Quick Help > Press and hold down the button which help information is required for.
> Hold the button down to read.
> Release the button to return to the previous scope state.
