Description Supplemental Information
External AM Input
Description Input provides low-frequency AM modulation to test port output
signal, or shifts the test port output. Zero volts input gives the power
level set by the instrument, a positive voltage gives a higher level,
and a negative voltage gives a lower level.
Connector BNC, female
Input Sensitivity 8 dB/V, typical
Bandwidth 1 kHz, typical
Input Impedance
1 kΩ, typical
External Detector Input
Description Input from an external, negative polarity diode detector provides
ALC for a test port remote from instrument's front panel
Connector BNC, female
Input Sensitivity -500 mV yields approximately -3 dBm at detector's input, typical
Bandwidth 50 kHz, typical
Input Impedance
1 kΩ, nominal
