external 10 MHz reference, and sets the phase difference between an external
master 5520A (using 10 MHz IN/OUT) and the NORMAL output. See
“Adjusting the Phase” and “Synchronizing the Calibrator using 10 MHz
IN/OUT” later in this chapter.
4-30. Setting Resistance Output
Complete the following procedure to set a synthesized resistance output at the 5520A
front panel NORMAL terminals. If you make an entry error, press Gto clear the
display, then reenter the value.
1. Press R to clear any output from the 5520A.
2. Connect the UUT as described earlier in this chapter under “Connecting the
Calibrator to a UUT.”
Note
Since this is a synthesized output, be sure the terminal connections from
the 5520A to the UUT are LO to LO and HI to HI.
3. Set the UUT to measure resistance on the desired range.
4. Press the numeric keys and decimal point key to enter the desired resistance output
(maximum six numeric keys). For example, 12.3456.
5. Press a multiplier key, if necessary. For example, press K.
6. Press Q.
7. The Control Display now shows the amplitude of your resistance entry. For example,
12.3456 kΩ (below).
nn096f.eps
8. Press E. The calibrator clears your entry from the Control Display and copies
it into the Output Display (below is typical).
nn097f.eps
9. Press O to activate the calibrator output.
The softkeys allow selection of three lead-compensation settings and ohms zero.
