Characteristics
The following characteristics are typical for the HP 54700-Series mainframes.
Channel
ADC Input Sources (simultaneous acquisition)
HP 54720A/D mainframe
4, each plug-in slot has its own 2 GSa/s
ADC with 16,384 point acquisition memory for the HP 54720A and
65,536 points for the HP 54720D.
HP 54710A/D mainframe
2, each plug-in slot has its own 2 GSa/s
ADC with 16,384 point acquisition memory for the HP 54710A and
65,536 points for the HP 54710D.
Best Accuracy Calibration
Performing the Best Accuracy Cal on a
channel just prior to a series of critical measurements will ensure the
most accurate results. This calibration adjusts the channel’s gain, offset,
and linearity and requires a specific plug-in to stay installed in a specific
mainframe slot.
Channel Skew Adjustment
The time skew between channels can be
manually eliminated all the way to the probe tip to 1-ps resolution.
Probe Calibration
A probe calibration routine automatically computes
the offset and the attenuation created by the probe attached to the
channel input.
Time base
Time Base Scale
100 ps/div to 20 s/div (in 1-2-5 or fine steps)
Time Base Position Range (auto sample rate and record length)
Pretrigger
0 to
−
1 s or one full screen width, whichever is larger.
Posttrigger
0 to 1 s or one full screen width, whichever is larger.
Time Interval Measurement and Trigger Interpolator Resolution
1 ps
Time Base Window
Scale:
1 ps/div to the main time base scale factor.
Position:
The window must always stay in the time window defined
by the main sweep.
