Programming the E5250A
Using the Capacitance Compensation Routine
Capacitance Compensation Routine This routine is an subprogram used to compensate for capacitance measurement
error caused by the E5250A with the E5252A matrix card installed. The subpr ogram
is used with Agilent 4284A Precision LCR Meter. You enter capacitance and
conductance data measured by the 4284A as a parameter, and this subprogram
returns the compensated value. This routine runs on HP BASIC.
Syntax: Ccompen_5250(Freq,L1,L2_h,L2_l,L3_ h,L3_l,C_m,G_m,C_c,G_c)
Parameter: Freq Measurement Frequency (Hz): 1000 Hz to 1000000 Hz (1 kHz to
1MHz).
L1 Length (in meters) of 16494A triaxial cable connected from E5252A
output to connector plate.
L2_h Length (in meters) of triaxial cable connected from connector plate to
DUT (High terminal of capacitor).
If you do not use triaxial cable, enter 0 for this parameter.
L2_l Length (in meters) of triaxial cable connected from connector plate to
DUT (Low terminal of capacitor).
If you do not use triaxial cable, enter 0 for this parameter.
L3_h Length (in meters) of coaxial cable connected from connector plate to
DUT (High terminal of capacitor).
If you do not use coaxial cable, enter 0 for this parameter.
L3_l Length (in meters) of coaxial cable connected from connector plate to
DUT (Low terminal of capacitor).
If you do not use coaxial cable, enter 0 for this parameter.
