Agilent E1439 Programmer's Reference

Functions listed alphabetically

AGE1439_ADC

inserts a 0.2 µF capacitor between the input connector and the 50 Ohm buffer

amplifier.

couplingPtr

points to the current value of the coupling parameter for an Agilent E1439 or group of
Agilent E1439s.

range

is a range index number which is transformed to a full scale voltage value. This function always
sets only the IF signal path range even if signalPath is set to AGE1439_BB_PATH. In baseband
mode the range is fixed at -21 dBm.

AGE1438_RANGE_MAX

sets the range to the maximum allowable.

AGE1439_RANGE_MIN

sets the range to the minimum allowable.

Signal inputs with an absolute value larger than full scale generate an ADC overflow error.

Range values are as follows.
