Phase: 000.0°
This setup menu lets the user edit the frequency and phase to be generated by the on-board synthesizer. Fre-
quencies from 1/8 Hz up to 10 MHz can be entered using four digits and a range. The range can be selected if
the „UP“ or „DOWN“ key is pressed while the cursor is positioned on the frequency´s units string. If the least
significant range has been selected valid fractions of the frequency are .0, .1 (displayed as 1/8), .3 (displayed as
1/3), .5 and .6 (displayed as 2/3). Selection of 1/3 or 2/3 means real 1/3 or 2/3 Hz, not 0.33 or 0.66. If frequency
is set to 0 the synthesizer is disabled.
The last line of the display lets the user enter the phase of the generated frequency from -360
◦
to +360
◦
with a resolution of 0.1
◦
. Increasing the phase lets the signal come out later. Phase affects frequencies less
than 10.00 kHz only, if a higher frequency is selected a message "(phase ignored)" informs the user that the
phase value is ignored.
