APPLICATIONS
Funcllon Generalors
The RG 501 ramp Is ideally suited to sweep the VCF or
VCO Inputs of most function generators. Selectable ramp
polarity provides for sweeping frequencies up or down.
Variable ramp amplitude and duration provide for con­
trolling the range and rate
01
the frequency sweep. The
RG 501 gate out signal provides lor synchronizing the
swept oscillator to the sweeper input.
A natural application of the RG 501 would
be
to pair it
with another membar of the TM
500
Series, the FG 501
Function Generator. The FG 501 frequency can be swept
over a 1000:1 range with the RG 501's a to 10 V linear
ramp. The output of the FG 501 can then
be
used to test
the response characteristics
01
frequency sensitive cir­
cuits. See Fig.
1-3.

RG 501 to AUTO TRIG and use the RAMP OUT signal to
drive the X-axis. A posilive-going ramp will sweep most
CRT displays from left to right. Vary the RAMP
AMPLITUDE for the desired sweep length. The la-volt
range of the AG 50' shOuld give a full-screen scan on Just
about any X-Y CRT display.
Use the GATE OUT Signal, which is coincident with the
RAMP OUT. to drive the Z - ax i s . The gate's
+3
V amplitude
is sufficient to unblank most CRT's and provide a usable
intensity level.
II the event to be displayed In the Y-axis meets the
triggering requirements, it can be used to externally
trigger the RG 501, producing a stable display when the
lEVEL control is correctly set.
Using lime marks and a graticule for the CRT display, a
calibrated
3%
time base can be generated. See Fig. 1-4.
