INPUTS (CHANNELS 1-8)
MAXIMUM SIGNAL LEVEL: Any channel to any channel or chassis (1–8): 30Vrms (42V
peak for AC waveforms) or 60VDC, 0.5A.
MAXIMUM POWER: 20W per module, 10W per channel (refer to 7711/7712 Manual
PA-818 for measurement considerations).
SAFETY: Conforms to European Union Directive 73/23/EEC EN61010-1, CAT I.
EMC: Conforms with European Union Directive 89/336/EEC; EN61326-1.
ISOLATION: Multiplexer to Multiplexer: >1GΩ.
Center to Shield: >1GΩ, <25pF.
Channel to Channel: >100MΩ.
CONTACT LIFE: 1×10

rated load (resistive load).
CONTACT POTENTIAL: <6µV.
CONTACT RESISTANCE: <0.5Ω (initial), <1Ω (end of life).
RISE TIME: <300ps (guaranteed by design).
SIGNAL DELAY: <3ns.
GENERAL
RELAY TYPE: High frequency electromechanical.
CONTACT CONFIGURATION: Dual 1×4 multiplexer, single pole four throw, Channels
1 and 5 are normally closed.
NOTES: One channel in each multiplex bank is always closed to the corresponding
OUT connector.
CLOSE CHANNEL: ROUTe:CLOSe allows a single channel in a multiplex bank to be
closed. ROUTe:MULTiple:CLOSe allows two channels (one in each bank) to be
closed at one time.
OPEN CHANNEL: ROUTe:OPEN:ALL closes CH1 and CH5 to OUT A and OUT B
respectively.
ACTUATION TIME: <10ms.
FIRMWARE: Specified for Model 2700 rev. B04, 2701 rev. A01, and 2750 rev. A03 or
higher.
CONNECTOR TYPE: Ten external rear panel SMA connectors.
MATING TORQUE: 0.9 N·m (8 in-lb).
ENVIRONMENTAL
OPERATING ENVIRONMENT: Specified for 0°C to 50°C. Specified for 80% RH at 35°C.
STORAGE ENVIRONMENT: –25°C to 65°C.
WEIGHT: <0.5kg (1.1 lb).
