8003 Technical Specifications
6
Rear Panel Inputs and Outputs
Sweep In (Sweep Voltage Requirements): (BNC connector). 0 to
+10 V nominal.
Blanking Input: (BNC connector) Used to blank the sweep
oscillator (swept signal generator) band switching points on the
8003 display. Voltage level: Blanked > 2 V; Un-blanked < 0.8 V
(typical)
Input 1: (BNC connector) TTL levels, used with some sweepers
(swept signal generator) to provide synchronization.
AC Modulation Output: (BNC connector) Provides drive to
modulation input on sweeper (swept signal generator) or
external modulator for use in AC detection mode.
Bias Output: (BNC connector). Programmable output voltage
used to display family of curves.
Voltage range: +/-10 V.
Current compliance: Source or sink 150 mA max.
System GPIB: (GPIB connector) Used to connect 8003 to GPIB
system controller.
Private GPIB: (GPIB connector) Used to connect 8003 to
dedicated signal generator, plotter or printer.
RS232 Port: Serial Communications Interface for driving legacy
serial printers and plotters.
Directional Bridges
The 80500 Series of Directional Bridges are designed specifically
for use with the 8003 to measure the return loss of a test device.
The bridges can be used in AC or DC detection mode. Each
bridge includes an EEPROM which has been programmed with
identification data for that bridge.
Bridge Frequency Response: Calibrated return loss
measurements using the 8003 can be frequency compensated
using the standard “Open/Short” supplied with the bridge.
Insertion Loss: 6.5 dB nominal from input port to test port.
Detector Polarity: Negative
Maximum Input Power: +27 dBm (0.5 W)
Directional Bridge Accessories: Open/Short is included
for establishing the 0 dB return loss reference during path
calibration.
