4.5.5. Measuring Energy of Rapidly Repeating Pulses
The standard Vega will only measure individual pulses
every 5 seconds or so. You can also calculate the
average energy of rapidly repeating pulses by measuring
average power on the power setting and using the
formula:
Average Energy per Pulse = Average Power / Pulse
Repetition Rate
For rapidly repeating pulses, you can use one of the Ophir
pyroelectric sensors, as long as the pulse energies do not
exceed the ratings of the pyroelectric absorbers. The
pyroelectric sensors are compatible with the Vega and
just have to be plugged in to be used.
For higher pulse energies, you can use the Ophir model
RP to measure both average power and exact individual
pulse energy of the rapidly repeating pulses.
See your Ophir agent or sales representative for
details.
4.5.6. Energy Log and Data Storage (See Figure 4.7 )
The Vega has the option of displaying successive energy
points in a scrolling vertical bargraph form. While
measurements are being taken, the Vega will record data.
Up to 250,000 points are stored See section 4.4.2.6.1 for
more information on data storage and handling.
Note:
For Thermopile sensors logging energy, there are no
setup options.
