Getting Started
Introduction
One of the first things you will want to do with your power meter is to switch it on and become acquainted with its front panel. The sections in this chapter prepare the power meter for use and help you get familiar with some of the front panel operations.
The front panel consists of both hardkeys and softkeys which allow you to select various functions and operations. When some hardkeys are selected the corresponding softkey labels are displayed on the power meter display.
If you are using the power meter remotely refer to the HP E4418B/4419B Programming Guide for remote operating details.

Turning On the Power Meter
The following steps show you how to turn on the power meter and verify that it is operating correctly.
1. Connect the power cord and turn on the power meter.
|
The front panel display and the green power LED light up when |
|||||||||
|
the power meter is switched on. The power meter performs it’s |
|||||||||
|
power on self test. If the self test is not successful the error |
|
|
|||||||
|
annunciator turns on. If this occurs contact your Hewlett-Packard |
|||||||||
|
Sales and Service office for instructions on returning the power |
|||||||||
|
meter to Hewlett-Packard for service. |

Caution |
This instrument has an autoranging line voltage input, be sure |
|
|
|||||||
|
the supply voltage is within the range of 85 to 264 Vac. |

|
|
Note |
If the power meter has been stored at extremely low temperatures |
|||||||||
|
outwith the operating range of the power meter, the display may |
|||||||||
|
take a few minutes to operate. |

3.Connect the power sensors.
Connect one end of each of the sensor cables to the power meter’s channel inputs and the other ends to the power sensors.
4.Making a measurement.
A minimum warm up time of 30 minutes is recommended before accurate measurements can be made.
Prior to making your first measurement you must zero and calibrate the sensor and meter combination. Refer to Chapter 2 for further information if you are not familiar with zeroing, calibrating or making measurements with a power meter.

1.Preset Local
This hardkey allows you to preset the power meter if you are currently working in local mode (that is, front panel operation). In local mode a confirmation pop up window is displayed prior to a preset being carried out. However, if you are in remote mode (that is, HP-IB, RS232 or RS422 operation), then pressing this hardkey places the power meter in local mode provided local lock out (LLO) is not enabled.
2. Hardkeys relating to the display layout.
This hardkey allows you to select the upper or lower measurement window on the power meter’s display. The window which is selected is highlighted by a shadowed box. Any measurement setup you create is implemented in the selected window.
This hardkey allows you to choose either a one or a two window display.

3.
This hardkey switches the power meter between on and standby. When the power meter is switched to standby (that is, when this hardkey has not been selected but the line power is connected to the instrument) the red LED is lit. When the power meter is switched on the green LED is lit.
Option 001 Battery: On standby with the battery installed and the ac power source disconnected the red LED is off.
4. “System/Inputs” hardkey with softkey menu.
The |

the general power meter system setup, (for example the HP-IB address) and also to softkey menus which effect the setup of the channel inputs. Refer to Chapter 3 for further information about this hardkey and it’s softkey menu.
5.Save Recall
This hardkey is the only one that is completely dedicated to the control of the power meter as a system. The only other hardkey
which affects system parameters is the System hardkey. Refer to

9.POWER REF Output.
The power reference output is a 50 Ω type N connector. The output signal of 1 mW at 50 MHz is used for calibrating the sensor and meter combination. Power meters configured with option 003 have the power reference on the rear panel.
10.Arrow hardkeys.
, , and hardkeys allow you to move the position of the cursor, select fields for editing, and edit alphanumeric characters. Refer to Chapter 3 for further information.
11. Menu related hardkeys.
More This hardkey allows you to move through all pages of a menu. The bottom right of the power meter display indicates the number of pages in the menu. For example, if “1 of 2” is displayed, pressing More moves you to “2 of 2”. Pressing More again moves you back to “1 of 2”.
Prev This hardkey allows you to move back one level in the softkey menu. Repeatedly pressing Prev accesses a menu which allows you to increase and decrease the display contrast.
12.Softkeys.
These four keys are used to make a selection from the menus.

1.The status reporting line displays five fields, three associated with either HP-IB, RS232 or RS422 status and two associated with error and warning conditions. The first field displays either “RMT” (remote, HP-IB, RS232 or RS422 operation) or “LCL” (local, front panel operation).
For HP-IB operation, the second field displays “TLK” if the power meter is addressed to talk or “LSN” if it is addressed to listen. The third field indicates an “SRQ” (service request).
For RS232 and RS422 operation, the second field displays “RX” when data is being received. The third field displays “TX” when the power meter is transmitting data.
The fourth field indicates “ERR” for any error conditions. The last field is used to report error and warning messages.
2.This field displays the channel setup being measured, either A, B, A/B, B/A, A-B or B-A.
3.The measurement data is displayed in either one or two rectangular windows depending on the setting of . Pressing

allows you to toggle between a one or two window display. When two windows are displayed and this hardkey is pressed the single window then displayed is the one which was previously highlighted with the shadowed box. On the two window display the measurement setup menus work on the window which is shadowed.
4.This is the measurement result field.
5.This field displays the units of measurement, either dBm, dB, Watts or %.
6.This window is configured to show an analog meter which displays the measurement result and the meter scaling.
7.This field displays the number of pages in the current softkey menu. For example, “1 of 2” indicates that there are two pages of
softkeys and you are on the first page. Pressing More moves you to page “2 of 2”.
8.Any softkeys available are displayed in these four fields.
9.This field displays the title of the menu. For example, when the power meter is initially switched on the “Contrast” menu is
displayed, and, if you press Zero “Zero/Cal” is displayed.
Cal
10.This field indicates if the measurement result is outwith the upper or lower limits set. If the measurement is within the limits this field is empty. If the measurement result is less than the minimum limit set, “Undr Lmt” is displayed. If the measurement result is more than the maximum limit set, “Over Lmt” is displayed. Refer to “Setting Measurement Limits”, on page 2-43 for further information.
11.This field displays “Rel” if relative mode is on. Refer to “Making Relative Measurements”, on page 2-34 for further information.
12.This field displays “Ofs” if an offset is set. Refer to “Setting Offsets”, on page 2-36 for further information.
13.This field displays “Rng Hld” if a range is selected. Refer to “Setting the Range”, on page 2-52 for further information.
14.This field displays “Dty Cyc” if a duty cycle is set. This allows you to measure the power of a pulsed signal. Refer to “Measuring Pulsed Signals”, on page 2-41 for further information.
15.Theinformation in this field is displayed on two lines and depends on thecombination of sensor type, sensor calibration table and frequency dependent offset table currently selected. Table 1-1 shows all the possible combinations for the two lines of the display. Find the table entry which matches your display and use the

This is equivalent to reference number 4 in Table 1-1 and when looked up in Table 1-2 shows that:
•the sensor type is 8480 series
•a sensor calibration table is selected (10)
•a frequency dependent offset table is selected(C).
