Basic 60Hz Power line monitoring setup/FFT

The purpose of this document is to instruct users on loading 2 preconfigured set ups and perform basic monitoring of a power line using a DS1000E/D series of oscilloscope.
Take extreme caution when connecting to power plugs and open wiring. There is an very high risk of electrocution and death. Voltages over 42V are considered 
dangerous and extreme caution should be used when connecting to such circuits. 
Load Setup

We have built a setup file (LineAnalyze.stp) that configures the scope to optimally record 60Hz signals on Channel 1. 

1.    Unzip LineAnalyze.stp file and move to the root directory of a compatible USB memory stick
2.    Insert USB memory stick into the DS1000E/D Oscilloscope USB port on the front of the instrument
3.    Press the Storage Key > Storage Menu select Setups 
4.    Under Storage Menu, Select External
5.    Select File in File Explorer using knob > Select Load using button
The scope will now be configured to monitor and record on channel 1. The settings are for a 60 Hz signal with a voltage range of 100V/division using a 10X probe setting. 
NOTE: The probe (RP-2200) must be set to the 10X setting before connecting to the signal source (line).
6.    Connect the probe to the signal of interest
Record Waveform:
Now we can record a number of waveforms. Each displayed waveform and subsequent items displayed on the screen are stored in a frame. Each frame is a Bitmap image. The scope is capable of storing 1000 frames in a record.
This setup (AnalyzeLine.stp) configures the scope  to store 1000 frames. It collects 1 frame per second (interval = 1s).

1.    Press the Utility button and “down arrow” grey key to get to page 2/2 on the Utility menu screens
2.    Press Record to enter the Record menu
3.    Press Operate to begin recording. 
NOTE: The scope will display the number of frames recorded. You can stop the recording by pressing the Operate button again. 
4.    You can also enable measurements at this time by pressing the Measure key in the Menu area of the front panel
5.    You can select the voltage and time measurements from the Measurements Menu. For line measurements, Vrms and Frequency are the most useful.
Playback individual frames
Here are the steps to playback the recording, select, and save a bitmap image of the display for an individual frame.
1.    Press the Utility key > Select Record from page 2/3 of the Utility menu
2.    Select Record Mode > Playback
3.    Change Play Mode from continuous loop to play > stop
4.    Go to page 2/2 of the Record menu (down arrow)
5.    Select the frame to view using the Current Frame key and the selection knob
6.    Once you have a frame you want to keep, you can save the bitmap image by following the Save Waveform instructions below
Saving a Waveform Image 
1.    Insert a compatible USB memory stick into the front USB input on the scope
2.    Press the storage key on the front panel
3.    Select Storage > Bitmap
4.    Save to the external drive by pressing External
5.    Press New File to save to a new file
6.    Press Save to write the file to the USB drive
Load the LineFFT.stp
Another useful attribute of the scope is to setup the Math function for FFT analysis. Using this feature provides visibility into the spectral/frequency content of the incoming signal.
LineFFT.stp is set up for a 60Hz signal.
1.    Unzip LineFFT.stp and put the file in the root directory of a compatible USB memory stick
2.    Follow the directions above for Load Setups to load the LineFFT.stp settings
3.    The FFT screen will appear. With the FFT, you can see the Frequency/div setting
4.    The center point of the screen can also be used to measure or indicate the frequency at that point. To move a peak to the center, rotate the Horizontal Position knob on the front panel of the scope.
