1-26. EQUIPMENT REQUIRED BUT NOT SUP-PLIED1-27. Display Mainframe

1-28. An HP 853A digital Spectrum Analyzer Display is recommended for use with the HP 8559A. The rear panel of the HP 853A mainframe provides the following output connections: HORIZ (SWEEP), VERTICAL (VIDEO), BLANK (PENLIFT), 21.4 MHz IF, and HP-IB interface con- nector.

1-29. An H P 180T-series display mainframe (180TR, 181T, 18lTR, or l82T) is also designed for use with the HP 8559A. In the HP 180T-series main- frame, the rear-panel auxiliary output connectors (AUX A, AUX B, AUX C, and AUX D) provide, respectively, Vertical Output, Pen Lift Output, 21.4 MHz IF Output, and Horizontal Output. A standard H P 180-series display mainframe (HP 18OA/AR, HP 180C/D, HP 181A/AR, HP 182A/C, or HP 184A/B) provides only horizontal, vertical, and blanking rear panel outputs. Furthermore, these outputs are attenuated and shifted in dc level. Unbuffered rear panel outputs (similar to the HP 180T- series) are provided only if Option 807 is installed.

1.30.Extender Cable Assembly

1-31. An Extender Cable Assembly (Figure 1-3), H P Part Number 5060-0303, allows operation of the HP 8559A outside the display mainframe. This provides access to the HP 8559A for necessary adjustments and some performance tests. This cable is also useful for troubleshooting.

1-32. EQUIPMENT AND ACCESSORIES AVAILABLE1-33. Input Limiter
response flatness is degraded by less than &0.5 dB

from 100 MHz to 12.4 GHz; the limiter is usable from 10 MHz to 18 GHz. Invut levels of 1 watt average or 75 watts peak can be tolerated.

1.35.Low Pass Filter

FIGURE 1-4. HP 11870ALOW PASS FILTER

1-36. The H P 11870A Low Pass Filter (dc-2.6 GHz) can be used with the HP 8559A to reject signals above 3 GHz by more than 60 dB for image-free measurements over the 10 MHz to 2.6 GHz range.

1-37. Modification Kit (Option 807 Connec- tions)

1-38. A modification kit, HP Part Number 00180- 69503, provides the materials and information necessary to install unbuffered rear panel connections (formerly included in Option 807) in the following display mainframes: HP 180A/AR, HP l8OC/D, HP 181A/AR, HP l82A/C, and HP 184A/B. Refer to Table 1-3 for a description of parts included in the modification kit.

1-39. Oscilloscope Camera
