Options and Accessories

Analyzer Options Available

Option 1D5, High Stability Frequency Reference

Option 1D5 offers ±0.05 ppm temperature stability from 0 to 55 °C (referenced to 25 °C),

and aging rate of ±0.5 ppm per year (typical).

Option 004, Source Attenuator (ET Only)

This option adds a 55 dB step attenuator that extends the output power range by allowing

lower power levels.

Option 007, Mechanical Transfer Switch (ES Only)

This option replaces the solid state transfer switch with a mechanical switch in the test

set, providing the instrument with greater power handling capability. Because the

mechanical transfer switch has less loss than the standard switch, the output power of

Option 007 instruments is 5 dB higher.

Option 010, Time Domain

This option displays the time domain response of a network by computing the inverse

Fourier transform of the frequency domain response. It shows the response of a test device

as a function of time or distance. Displaying the reﬂection coefﬁcient of a network versus

time determines the magnitude and location of each discontinuity. Displaying the

transmission coefﬁcient of a network versus time determines the characteristics of

individual transmission paths. Time domain operation retains all accuracy inherent with

the correction that is active in the frequency domain. The time domain capability is useful

for the design and characterization of such devices as SAW ﬁlters, SAW delay lines, RF

cables, and RF antennas.

Option 012, Direct Access Receiver Conﬁguration (ES Only)

This option provides front panel access to the A and B samplers. This allows direct access

to the sampler inputs for improved sensitivity in applications such as antenna tests, or for

the insertion of attenuators between the couplers and samplers to allow measurements of

up to 1 Watt (+30 dBm) at the input of the test ports. Direct access to the B sampler

provides a test configuration for the analyzer that gives increased dynamic range in the

forward direction.

Option 085, High Power System (ES Only)

This option is designed to permit the measurement of high power devices. With an

external power amplifier, this configuration will allow up to 20 Watts (+43 dBm) of output

at the test ports. The maximum test port input power is 1 Watt (+30 dBm) CW, but

jumpers on the front panel allow the insertion of high power attenuators or isolators. This

allows test device output levels up to the power limits of the inserted components.
