Synthesizer Frequency
This rotary control (along with an entry
box) is used to select a fixed frequency. A frequency value may be
selected by pointing the rotary control and dragging it around to the
left or right until the desired frequency is reached. The LOCKED
indicator will illuminate when the Synthesizer settles on the target
frequency. The value is displayed in the entry box below the rotary
control. The entry box value may be changed by highlighting the
number and entering in the desired value or by using the up/down
arrows to the left of the entry box. The default frequency is 10,000
MHz. Refer to the Synthesizer’s data sheet for applicable frequency
range. Data sheets are located on the Phase Matrix website (www.
phasematrix.com).
LOCKED
This indicator illuminates when the Synthesizer settles
on the target frequency.
Lock Recovery
When this check box is selected, the Synthesizer
will automatically attempt to recover a lost or unestablished frequency
lock. Three attempts will be made to recover the lock. The LOCKED
indicator will no longer illuminate if the Synthesizer cannot recover
the frequency lock. The lock recovery function is on by default.
Synthesizer Power
This rotary control (along with an entry
box) is used to select output power. A power value may be selected
by pointing the rotary control and dragging it around to the left or
right until the desired power is reached. The value is displayed in
the entry box below the rotary control. The entry box value may be
changed by highlighting the number and entering in the desired val-
ue or by using the up/down arrows to the left of the entry box. The
default output power is +15 dBm for the FSW-0010 and +13 dBm
for the FSW-0020. The FSW-0010 Synthesizer provides a leveled
power response from -25 dBm to +15 dBm, and the FSW-0020
model provides a leveled response between -10 dBm and +13 dBm.
Synthesizer Power OUTPUT
This button enables the user to choose
between RF power output on or off. By default the OUTPUT button is
off. When the OUTPUT button is on, the button will illuminate.
Blanking
When this check box is selected, RF output power will
be disabled while the Synthesizer is switching between frequencies.
Blanking is off by default.
Pulse
This button is used to select pulse modulation. To utilize
pulse modulation, connect a pulse-modulation source to the
Synthesizer’s Pulse input connector located on the front panel (see
Figure 32) and select the Pulse button on the main control panel.
The button will illuminate to indicate that pulse modulation is on,
and the Synthesizer will switch the output power on and off using
5-volt logic (i.e., +5 V = 0n and 0 V = off). Pulse input uses an
