Isolation calibration of CH 1 requires two load loads to connect CH 0 and CH 1, respectively, to obtain the best isolation, usually with only one set of calibration loads for port 0, and to connect the load Calibrator to CH 1, CH 0 to remain open, and then press the ISOLN menu to calibrate. Load Port 2 with 50 Ohm terminator (both ports terminated), press ISOLATION. This will bring up the calibration window. 0 MHz) and Band 3 (4. 050 MHz with 1 kHz step (10000 points) and with 5x averaging: scanraw 0 50000 1000 10000 5 where: 0 - channel CH0 (S11). This one like the SV1AFN is also based on the ADE-1 mixer, but uses 125 MHz oscillator and is based on an open source design. Also, I use Matlab to plot the 4191A's data captured via GPIB). are waved and part of the calibration. For the female calibration part, the short circuit (SHORT) is used for short-circuiting the solder on the back, the (LOAD) 50 ohm load is applied to the two 100 ohm resistors, and the open circuit (OPEN) is used for the open circuit. Short: Short load on S11 port. Cabe destacar que a la hora de comprarlo hay que tener cuidado, pues deberemos de prestar mucha atención en que venga con los tres tapones de calibración y batería interna. Actually, two 50 Ohm pieces are useful for the "Isolation" step of the calibration sequence.
