LogicView™ – MSO Capability in M1™
How would I benefit from this feature?
- View the logic state of a 32-bit (max) wide bus with timing resolution of 1 ns or better1 on each channel
- View all available analog channels and up to 32 timing analyzer signals simultaneously
- In the x-axis synchronized mode, perform cross domain debug like never before possible
- Use M1™ for automated bus compliance measurements using TestScript™ to verify/debug timing2 on all channels simultaneously and check voltage3 specifications, including eye pattern tests, on up to 100 channels simultaneously
- Quickly verify proper bus functional and parametric behaviors
- Markers will show hex and/or binary readout of the digital state
- Toggle on/off groups of 4 logic channels at a time with the Pod buttons
- LogicView lets you turn individual logic channels on/off (toggling them in M1 also toggles them in the scope)
Description
LogicView for lets you view and analyze up to 32 digital channels in addition to
all analog channels. It lets you perform cross-domain debugging like
never before. Individual channels, or groups of channels, can be
separately enabled/disabled to speed processing. Both analog and logic
channels can be used for trigger conditions and in measurements,
although the resolution available from logic signals depends on the
MSO oscilloscope, and is typically less that that available for the
analog channels. Both binary and hex representations are available for
the logic states at any point in time.
New
TestScripts that take advantage of this capability have been developed.
For example, a Micron Flash Memory TestScript™ is available on our Forum .
This TestScript tests the entire physical layer specification for this
part and greatly reduces the test time due to more pins being tested at
once than ever possible with a 4 channel scope alone. The Mixed Signal
Oscilloscope, combined with the TestScript capability, provides users
with an outstanding combination of features to improve measurement
throughput by 2 orders of magnitude.
1
The Bus Width and Resolution of the timing analyzer are determined by
the particular Mixed Signal Oscilloscope (MSO) being used.
2 Timing
measurements on the logic channels are lower resolution measurements
than on the analog channels because the sample rate of the timing
analyzer, in the MSO, is usually limited to something much less than
the sample rate of the analog channels on the MSO. Logic channels are
also limited in that no software interpolation is possible; i.e. the
hardware resolution is the total resolution.
3 Voltage
measurements are not possible on the logic channels of the MSO. The
user must use the analog scope channels to measure eye patterns and
voltage measurements.
