1. Separate the two instrument sections.
2. Attach a completed service tag to each of the sections.
3. Wrap each section in antistatic plastic to reduce the possibility of damage caused by electrostatic discharge.
4. Use a strong shipping container. A double-walled, corrugated cardboard carton of 159-kg (350~lb) bursting strength is adequate. The carton must be large enough and strong enough to accommodate the instrument. Allow at least 3 to 4 inches on all sides of the instrument for packing material.
5. Surround the instrument with 3 to 4 inches of packing material, to protect the instrument and prevent it from moving in the carton.
If packing foam is not available, the best alternative is S.D.-240 Air
Cap from Sealed Air Corporation (Hayward, California 94545). Air
Cap looks like a plastic sheet filled with l-l/4 inch air bubbles. Use the pink (antistatic) Air Cap to reduce static electricity. Wrapping the instrument section several times in this material should both protect the instrument section and prevent it from moving in the carton.
6. Seal the carton with strong nylon adhesive tape.
7. Mark the carton
FRAGILE, HANDLE WITH CARE.
8. Retain copies of all shipping papers.

Installation 2-19
To Set the HP-IB
Address
The HP-IB address is used in remote programming to identify the instrument. The decimal address is preset at the factory to 18 (ASCII
2R). Addresses may be decimal 0 through 30. The HP-IB address can be changed manually from the instrument’s front panel, remotely via the HP-IB bus, or by setting the instrument’s internal address switch.
The internal address switch is comprised of five switches located on the Al5 controller assembly in the RF section. These switches
(A15SWl A2 - A6) determine the HP-IB address to be used at instrument “power-up.” These switches are preset at the factory to binary 11111 (decimal 31), which sets the instrument to the HP-IB address stored in RAM memory (or to the default value 18, if the contents of RAM memory are ever lost due to a battery failure, and so on). If the switches are set to a value other than 31, the instrument will always reset the HP-IB address to this value at power-up.
From the Front Panel
From the HP-IB Bus
To enter a new address from the front panel:
1. Press CSHIFT) (EELi] p.
2. Use the number keypad to enter the new decimal address.
3. Terminate the entry by pressing IHz). This changes the current
HP-IB address and stores the new address value in RAM memory.
To enter a new address via the HP-IB bus, refer to the KSP command in the
HP 8568B Operating and Programming Manual.
From the HP-IB
Address Switch
Warning
Changing the HP-IB address by resetting the address switch
on the Al5 Controller assembly requires the removal of the RF
section’s protective bottom cover. This should be performed
only by a qualified service person. Refer all such servicing of the
instrument to qualified service persons.
2-20 Installation
1. Disconnect the ac line cord from the RF section.
2. Using a screw driver, remove the two RF-section rear panel bumpers. See callout 1 in Figure 2-15.

5. Locate the address switch A15SWl as shown in Figure 2-16 and Figure 2-17. Change the switch’s setting according to the information given below.
The switch comprises six segments, Al through A6. Al must always be set to logic 1. Each of the remaining five segments, A2 through A6, corresponds to one of the digits of a 5-digit binary equivalent of the address. See Figure 2-17. The switch is preset at the factory to binary 11111 (decimal 31). This is a special code which commands the instrument to use the last input address
(stored in memory) either from the front panel or from HP-IB.
You can reset the switch to correspond to the binary equivalent of any desired decimal value indicated in Iable 2-l. For example, if the desired address is 4, the A15SWl would be set as shown in
Figure 2-18.
Note
Observe that although 2’ is the far-right digit in Table 2-1, 2’ is represented by the far-left segment of the address switch.

Dynamic Range
Spurious Responses
For total signal power of c-40 dBm at the input mixer of the analyzer, all image and out-of-band mixing responses, harmonic and intermodulation distortion products are >75 dB below the total signal power for input signals 10 MHz to 1500 MHz, >70 dB below the total signal power with input signals ~10 MHz.
Input mixer level is defined as the input attenuation subtracted from the total signal power at the input connector.

Note
For typical second and third order distortion characteristics, see
Figure 4-4 in Chapter 4, “Performance Characteristics.”
Dynamic range due to Third Order Intermodulation Distortion and noise level can be calculated from 2/3 [TOI - displayed average noise level]. For example, at 900 MHz the analyzer’s specified dynamic range when using the 10 Hz resolution BW is: 2/3 [ + 10 dBm - (-135 dBm)] = 2/3(145) = 96.7 dB.
Two-tone intermodulation distortion products can be calculated from
2(TOI - signal level). For example, for two tones at -30 dBm, the intermodulation products for a +5 dBm TO1 will be:
2[ + 5 dBm - (-30)] = 70 dB down.

4 Assuming calibration signal is used to calibrate the reference level at -10 dBm and the input attenuator is fixed at 10 dB.
When the error-correction function is used, amplitude uncertainty is introduced because additional IF gain is used to offset the amplitude errors caused by resolution bandwidth switching, log scale switching, and RF gain errors.
