Insertion Loss Mode; Data Storage - Deepace KC901V Manual

2.9 Insertion Loss Mode

Insertion loss test is actually a single point S21 measurement.
Firstly, enter field strength mode, then choose "Insertion" on the bottom right
corner on the screen. After choosing it, there will be a "GEN ON" sign. Data on the
left side of the screen is the absolute level value. However, the data on the right is the
relative level. To calibrate, connect the cable without the DUT to each RF port, and
then choose AUTO CAL in the menu. After calibrating, connect the device under the
test to the testing cable. Reading at the left is insertion loss.
2.10 Data Saving
If data needs to be saved, insert a micro SD (TF) card into the instrument.
In test function, press combined key SHIFT+1 to save the current screenshot as
well as save the test results and settings as a chart.
The file names will be set automatically by system. If you want to set the file
names by yourself, use the combined key SHIFT+3.
While connecting the instrument to PC via USB, the instrument is detected as a
USB flash drive. In this case, the SD card is already taken over by the PC, therefore
when connecting to PC, data can't be saved.
In S11, if you need to save the files as S1P format or save all original testing
points, you need to save it in Smith chart mode.

tory Reset" (ALL RESET) to reset the parameter. Attention:
