MUL TIPLIER
Invoking the MUL TIPLIER function (pressing the 4
SHIFT
5 key and then the
4 FREQ 5 key) allows you to enter a multiplier value so that the frequency
display will indicate the frequency at the output of a frequency multiplier .
N O T E
External equipment is required for frequenc y multiplication.
When 4 SHIFT 5 , 4 FREQ 5 is pressed, the multiplier value will be displayed across
the display in the following format:
FREQUENCY MULTIPLIER XXX
where XXX is the multiplier value . The allowable range for multiplier values
is 1 to 100. The preset value is 1 and the preset up/down arrow increment
value is 1.
Entering a frequency multiplier value is useful when generating
millimeter-wave signals with external multiplier equipment. The display
shows the frequency at the output of the external frequency multiplier , not at
the synthesizer RF OUTPUT connector .
F or example , assume a frequency of 30 GHz is required. The synthesizer
cannot generate a 30 GHz signal directly , but a frequency doubler can be
connected at the RF OUTPUT connector to multiply a 15 GHz signal by two .
Setting the multiplier value to two allows you to display the frequency at the
output of the multiplier on the synthesizer . Setting the multiplier value to
two will display 30 GHz, while the synthesizer is actually generating 15 GHz.
Entering a new frequency of 32 GHz will set the synthesizer to 16 GHz.
