= LEVEL
DIAGRAM
OF TS-515
Receiver
Fig. 16 shows a level diagram in the receiving portion.
® Each value in Fig. 16 shows the attenuator
reading of
SSG
taken when the pointer of S meter starts to move
slightly from '0"".
® The values indicated by Vrms show the measured vaiues
by the RF vacuum tube voltmeter.
® Before
the receiver
portion
is checked,
the null-point
must be surely set by variable resistor of S meter on the
IF unit.
@ As shown
in Fig. 15 SSG must be used with a ceramic
capacitor of 0.01uF (S00WV).
2. Transmitter portion
Fig. 17
shows
a
level
diagram
in the
transmitter
portion,
[Note]
@ Each value in Fig. 17 shows the measured value by the
RF vacuum tubes voltmeter having an input capacitance
of Jess than 3pF.
e Voltage up to the first grid of $2001
show the values
measured under the condition the SG switch is in OFF.
® Voltages with no special note show the values in rms.
@ The
values
with
mark
* include
the heterodyne
input
voltages and signal voltages.
e@ Set the MODE switch to the position "CW".
