An Example of Trapping
1. The leftmost frequency on the screen is the stop frequency for the trap function.
(19.979MHz)
2. The rightmost frequency on the screen is the start frequency for the trap function.
(19.998979 MHz=19.9792(1+1000E06))
3. A phase is continuously measured at the rightmost frequency on the screen.
4. When deposition proceeds and the phase becomes 0, E5100A/B option 022 outputs 8 to the
I/O port.
5. E5100A/B option 022 moves the measured point to the second point from the right (it
changes the measured frequency) and measures the phase .
6. Since the output data is not specied for this I/O port, the output data to the I/O port
remain unchanged when the phase becomes 0.
7. E5100A/B option 022 goes to the third measured point from the right to perform the trap
function.
8. At the 4th measured point from the right, E5100A/B option 022 outputs 4 to the I/O port.
9. E5100A/B option 022 continues to measure at the rest of measured points until it reaches
the stop frequency for the trap function.
Note
Y ou can specify at which measured point and what data to output to the I/O
port
As soon as E5100A/B option 022 completes the trap function on the channel 1, it performs a
normal frequency sweep on the channel 2 to verify the resonant point. When E5100A/B option
022 completes the sweep , it calculates the resonant frequency and resonant impedance and
displays them at the lower half of the screen. (Figure G-3)
There are 4 waveforms on the screen because the measurement screen at the upper half of the
screen displays the waveforms of the channel 1 over those of the channel 2.
