E
Cable length coefficient
The coefficient corresponding to the setting for measurement cable length is obtained from the measurement
cable length table and then multiplied by the basic accuracy.

IM3533-01 guaranteed accuracy range (frequency)
0 m / 1 m / 2 m / 4 m: Up to 200 kHz (no limit)
F
DC bias coefficient
The coefficient corresponding to the setting for ON/OFF of DC bias is obtained from the DC bias coefficient
table and then multiplied by the basic accuracy.
G
Temperature coefficient
The coefficient corresponding to the operating temperature is obtained from the operating temperature coeffi-
cient table and then added to the basic accuracy.
