Characteristic Performance Requirement
Supplemental Information
1st LO and 2nd LO
Provides access to the output of the respective
local oscillators (1st LO +7.5 dBm minimum to
a maximum of +15 dBm. 2nd LO —22 dBm
minimum to a maximum of +15 dBm). These
ports must be terminated in 50 Ω at all times
VERTICAL
0.5 V, ± 5% of signal per division of video above
and below the centerline.
Source impedance approximately 1 kQ
HORIZ OUT
0.5 V/Div either side of center.
Full range -2.5 V to +2.5 V, ±10%
Source impedance approximately 1 kn
PEN LIFT
IF OUT
TTL compatible, nominal +5 volts to lift pen
Access to the 10 MHz IF. Output level is ap
proximately — 16 dBm for a full screen signal at
—30 dBm reference level. Nominal impedance
approximately 50 Ω
IEEE Std 488-1978 Port (GPIB)
492P
In accordance with IEEE 488 standard
PROBE POWER
Provides operating power for active
probe systems. Output voltages and
pin-out are shown in Fig. 1-1.
