61. Program the calibrator to 200mA DC, then
press then ENTER key. The Model 2001 will display the
following while calibrating:
Low-Level Cal - Step 13 of 15
62. The Model 2001 will prompt for the next calibration sig-
nal:
C2 ADC
63. Program the calibrator to 2A DC, then press the
ENTER key. During calibration, the instrument will dis-
play the following:
Low-Level Cal - Step 14 of 15
64. The unit will then prompt for the last calibration signal:
Connect 2 V at 1 Hz
65. Put the calibrator in standby, then disconnect it from the
Model 2001 INPUT and AMPS jacks; connect the syn-
thesizer to INPUT HI and LO, as shown in Figure 2-5.
66. Set synthesizer operation modes as follows:
FCTN: sine
FREQ: 1Hz
AMPTD: 2Vrms
MODE: CONT
67. Press the Model 2001 ENTER key. The instrument will
display the following while calibrating:
Low-Level Cal - Step 15 of 15
68. After step 15 is completed, the instrument will display
the following message to indicate that calibration has
been completed:
CALIBRATION COMPLETE
69. Press ENTER. The instrument will prompt you to enter
the calibration date:
CAL DATE: 01/01/92
70. Use the cursor and range keys to set the date as desired,
then press ENTER. Press ENTER a second time to con-
firm your date selection.
71. The Model 2001 will then prompt you to enter the cali-
bration due date:
NEXT CAL: 01/01/92
72. Use the cursor keys to set the date as desired, then press
ENTER. Press ENTER again to confirm your date.
73. The Model 2001 will then display the following mes-
sage:
CALIBRATION SUCCESS
74. If you wish to save the new calibration constants, press
ENTER. If, on the other hand, you wish to restore pre-
vious calibration constants, press EXIT.
75. Press EXIT as necessary to return to normal display.
NOTE
Calibration will be locked out automati-
cally when the calibration procedure is
completed.
2.10.4 IEEE-488 bus low-level calibration
procedure
Follow the steps below to perform low-level calibration over
the IEEE-488 bus. Table 2-7 summarizes calibration com-
mands for the procedure.
