Agilent E1439 Programmer's Reference
Functions listed alphabetically
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.
