Hp/agilent 87050A-H47 s-parameter test set, 300KHZ to 6


S-Parameter Test Set, 300kHz to 6 GHz, Multiport
The 87050A-H47 is based on the 85047A S-Parameter test set and is designed to
work with the 8753C/D network analyzer. It has been modified to provide
higher power, up to +30 dBm, at test ports 1 & 2. It includes two mechanical
SP4T switches which gives it the ability to select between normal S-Parameter
test set operation or one of three external sources (input of +30 dBm, 7 Vdc,
1 watt max.) and one of three external measurement devices, without changing
connections to the device under test. The control lines for these two internal
switches are routed to a 25 pin sub-D miniature (male) connector on the rear
panel. The two switches require +24 Vdc on one line (to power the switch),
four drive lines (TTL level), four sense lines, one ground line, ane one
indicator ground line (for the sense lines). The switch control/programming
The rear panel also provides two BNC connectors for Port 1 and Port 2 bias
(fused at 1 amp), two BNC connectors for LIMIT TEST TTL OUTPUT and TEST
SEQUENCE TTL OUTPUT, and another 25 pin sub-D miniature (female) connector
for the network analyzer interconnect.
