The :DEMO:FUNCtion command selects the type of demo signal:
Demo Signal
Function
Demo 1 Terminal
SINusoid
5 MHz sine wave @ ~ 6 Vpp, 0 V offset
NOISy
1 kHz sine wave @ ~ 2.4 Vpp, 0.0 V offset, with ~ 0.5 Vpp of random noise
added
RINGing
500 kHz digital pulse @ ~ 3 Vpp, 1.5 V offset, and ~500 ns pulse width with
ringing
SINGle
~500 ns wide digital pulse with ringing @ ~ 3 Vpp, 1.5 V offset
Press the front panel
Set Off Single-Shot
softkey to cause the selected
single-shot signal to be output.
CLK
3.6 MHz clock @ ~2 Vpp, 1 V offset, with infrequent glitch (1 glitch per
1,000,000 clocks)
GLITch
Burst of 6 digital pulses (plus infrequent glitch) that occurs once every 80 µs @
~3.6 Vpp, ~1.8 V offset
BURSt
Burst of digital pulses that occur every 50 µs @ ~ 3.6 Vpp, ~1.5 V offset
RUNT
Digital pulse train with positive and negative runt pulses @ ~ 2.9 Vpp, 1.5 V
offset
TRANsition
Digital pulse train with two different edge speeds @ ~ 3.5 Vpp, 1.75 V offset
RFBurst
5-cycle burst of a 10 MHz amplitude modulated sine wave @ ~ 2.6 Vpp, 0 V
offset occurring once every 4 ms
LFSine
30 Hz sine wave @ ~2.7 Vpp, 0 V offset, with very narrow glitch near each
positive peak
FMBurst
FM burst, modulated from ~100 kHz to ~1 MHz, ~5.0 Vpp, ~600 mV offset.
NFC
~2.4 Vpp unmodulated carrier amplitude, ~1.8 Vpp maximum modulated
amplitude, ~0.0 V offset
CXPI
CXPI, ~2.5 Vpp, ~1.25 V offset, frame IDs: 20, 21, and 29 (with a frame error).
ARINc
ARINC 429, 100 kbps, ~5 Vpp, ~0 V offset.
