There are two
types of PML series passive probes, high impedance
(10 MΩ) specifications and low impedance
specifications (500 Ω/5 kΩ). We also have many
tools to avoid probing troubles due to high integration of LSI. ..
Now let's think about probing the signal and ground lines.
For example,
do you suffer from shorting with the next IC pin during probing?
There is an "IC cap" that prevents shorts between pins.
Probing a high-density, small-sized, high-pin count device often results in a
short circuit with an adjacent pin, causing electrical damage. Here, we
recommend probing with an "IC clip" that can reliably probe the
pins.
For example, 0.5mm, 0.65mm, 0.8mm, 1mm, 1.27mm IC caps with guards are
provided to prevent short-circuiting between pins. Take the probe hook and
attach it to the IC cap. You can realize safe measurement according to the
pin spacing.
Also, is the
signal to be measured output from the IC far from the ground?
Here we will use the ground blade.
Probing problems are often caused by ground leads. A commonly used
ground lead is a 10 cm lead with a crocodile clip attached. It is also
effective to make the ground lead as short as possible to realize a
measurement method with less waveform distortion due to probing.
The PML series probes come with a ground blade and
copper foil. By mounting the
copper foil on the IC and connecting the ground pin of the IC to the copper
foil, you can make a short distance from any pin to the ground line. A tool
that can be connected is also attached. By attaching a ground blade to
the tip of the probe on the ground side and attaching an IC cap that fits
between the pins, you can easily perform probing with less waveform
distortion.
Do you want
to measure two or more signals at the same time?
A two-foot positioner is useful for capturing two or more signals. Since
it is hands-free, you can concentrate on operating the measuring instruments
and observing waveforms. Since the positioner body has an insulated mold
structure, you can perform probing with confidence without shorting the
board. It comes with 2 signals, 4 signals and powerful accessories that
you can measure freely.
The two-leg positioner can probe PMK's 5mm probe,
2.5mm probe, etc. hands-free. |
