0.5 V/GHz OUT This rear panel BNC connector can be used as one of the
inputs to a recorder . It produces a DC voltage output that
varies linearly with the frequency currently at the RF
OUTPUT connector . F or example , if the current frequency
setting is 5.5 GHz, the voltage at this connector would be
2.75 V . The nominal source impedance is 250.
10 MHz IN This rear panel BNC connector accepts a 10 MHz, 0 to +10
dBm reference signal for operation referenced to an external
time base . The nominal input impedance of this input is
50. This connector detects when a valid reference signal is
connected to it and automatically switches from internal to
external reference operation.
10 MHz OUT This rear panel BNC connector provides a 3 dBm 63 dB , 10
MHz signal derived from the internal frequency standard of
the synthesizer . The nominal source impedance is 50.
ALC IN This front panel BNC connector allows the synthesizer to be
externally leveled. It is used with external power meter
leveling or external diode leveling. The leveling signal at
this input must be in the 61V range . The nominal input
impedance is 150 k. The damage level is +12 V or 012
V .
RF OUTPUT The standard front panel RF OUTPUT connector is a Type-N
precision connector . When Option 1E9 is installed, this
front panel connector is a 3.5 mm precision connector . The
nominal source impedance is 50.
When making connections to this connector , carefully align
the center conductor elements , then rotate the knurled
barrel while mating components remain still. Tighten the
barrel until rm contact is made .
T ake care when working with this connector . If the
connector is mechanically degraded in any way , high
frequency losses can occur . Refer to application note 326,
Coaxial Systems - Principles of Microwave Connector Care
(HP part number 5954-1566) for more information.
