6 REF IN connector
Female BNC connector, accepts a –3.5 to
+20 dBm signal from an external reference oscillator that is
within ppm. The nominal input impedance is 50 ohm.
The connector accepts 2MHz, 5MHz, 10 MHz signal according
to your selection.
7 PULSE MOD IN connector This BNC input connector accepts a
TTL signal for pulse modulation. The damage level is 5 Vrms.
8 MOD IN connector This BNC input connector accepts a
1.0 +
2% V (peak) signal for AM, FM, and phase modulation.
For all these modulations, +1.0 Vpeak produces the indicated
deviation or depth. The damage level is 5 Vrms.
9 Q IN connector This female BNC input connector accepts an
external quadrature- phase component of an I/Q baseband
signal. The signal level is = 0.5 Vrms for calibrated
output level. The input impedance is 50 Ohm. The damage
level is 1 Vrms.
10 I IN connector This female BNC input connector accepts an
externally
in-phase component of an I/Q modulation signal.
It has the same characters with the Q baseband signal.
11 VGA connector connects to an external monitor or projector.
12 USB device connectors connect with external USB devices,
such as a USB memory stick.
