About this Manual
We’ve added this manual to the Agilent website in an effort to help you support your product. This manual is the best copy we could find; it may be incomplete or contain dated information. If we find a more recent copy in the future, we will add it to the Agilent website.
Support for Your Product
Agilent no longer sells or supports this product. Our service centers may be able to perform calibration if no repair parts are needed, but no other support from Agilent is available. You will find any other available product information on the Agilent Test & Measurement website, www.tm.agilent.com.
HP References in this Manual
This manual may contain references to HP or Hewlett-Packard. Please note that Hewlett-Packard's former test and measurement, semiconductor products and chemical analysis businesses are now part of Agilent Technologies. We have made no changes to this manual copy. In other documentation, to reduce potential confusion, the only change to product numbers and names has been in the company name prefix: where a product number/name was HP XXXX the current name/number is now Agilent XXXX. For example, model number HP8648A is now model number Agilent 8648A.

Warning
Remove the HP 70340A module from the MMS and attempt to power-up the mainframe,
itself.
If the mainframe power light does not come on, the mainframe is bad. If the mainframe
does power-up, the fault lies with the HP 70340A.
If the mainframe power light is on, but the ventilation fan does not start:
Set the mainframe LINE (Mains) switch to OFF.
Checkforblockage of the fan intakes at the bottom rear of the mainframe.
Refer to your MMS mainframe manual.
For continued protection against fire hazard, replace the fuse with one that is
the same type and rating.

Performing Fundamental Operations
This chapter describes basic Modular Measurement System, MMS, op erations. Its purpose is
to quickly familiarize you with the general operation of the HP 70340A and HP 70341A within
the MMS. For more detailed information, refer to the display op erating manual or the \70000
Protocol and Functional Specications" document.
Instruments that are part of the MMS have some important dierences from stand-alone
instruments. MMS instruments are composed of plug-in mo dules, the power supply is
distributed, and the mo dules communicate with each other using the Modular System
Interface Bus, HP-MSIB.

To Enter Data with the Numeric Keypad
The display's numeric keypad combined with the units terminator softkeys provide one wayto
enter function parameters.
1.
Select a function softkey.
The function must haveanumeric value (parameter) asso ciated with it in order to enter
new data with the numeric keypad. AMPLITUDE, FREQUENCY MULTIPLIER, and
CW FREQUENCY are examples of functions with parameters.
When you select a function that requires numeric data, its key label appears in inverse
video (highlighted) and the data entry box at the bottom of the display indicates the
function, its currentvalue, and any associated units. For example, if CW frequency is the
selected function with a currentvalue of 2 GHz, the data entry box indicates:

If the signal generator does not display/output the CW FREQUENCY entered:
Check that the FREQUENCY MULTIPLIER value entered is correct.
If the FREQUENCY MULTIPLIER is a value other than 1, the resolution of the
instrumentmay not allow the exact frequency entered.
For example, if you require an ouput of 40 GHz and are using a frequency multiplier of 3,
the signal generator should output a value of 13.333333333 GHz. The closest value that the
signal generator can output, however, is 13.333333000 GHz since it has 1 kHz resolution.
Thus, the signal generator will display 39.999999000 GHz, not 40.000000000 GHz, as the
actual output at the multiplier.
Check the \Specications and Options" chapter to makesurethatyou have not set the
parameter out of the range of the sp ecication.

Generating Signals
This chapter provides pro cedures for generating signals with the HP 70340A (and HP
70341A.) When the term \signal generator" is used, it refers to either the HP 70340A or the
HP 70340A/41A combination.
Along with signal generation procedures, methods for performing external leveling and atness
correction are included. The steps in these procedures assume that you are familiar with
basic signal generator and display op erations. If you want to become more familiar with the
Modular Measurement System, refer to the chapter, \Performing Fundamental Operations." If
you require additional programming information, refer to the
part number H2325-90001) or the \Programming Commands" chapter in this manual.

To Generate an AC FM Signal
You can generate an AC coupled frequency modulated (AC FM) signal at any carrier
frequency within the signal generator output frequency range. AC coupling is useful when the
modulating signal has a minimum rate of greater than 1 kHz in order to achieve frequency
accuracy and stability.
Generating an AC FM signal requires the following external equipment.

The Knob resolution can be changed using the Mo dify Step functions.
However, the multiplied signals frequency resolution is further limited
due to the FREQUENCY MULTIPLIER function. For instance, if the
FREQUENCY MULTIPLIER is set to 3, and the signal generator resolution is
1 kHz, the resulting resolution is 3 kHz.

To Generate Simultaneous Log AM and Pulse Modulation
You can generate simultaneous logarithmic AM and pulse modulation by applying a voltage
waveform to the signal generator
(or, if your instrument has Option 1E2, internal or gated pulse) modulation. The resulting
signal at the signal generator

To Use the Flatness Correction Routine
When the FLATNESS CORRECTION routine is on, the signal generator performs a
calibration pro cess that corrects for external losses or power variations in an external signal
path. In order to use FLATNESS CORRECTION, the signal generator must rst run the
CALIBRATE FLATNESS CORRECTION routine. During the CALIBRATE FLATNESS
CORRECTION routine, an HP 437B, HP 438A, HP 70100A, or a SCPI compatible p ower
meter, that is under control of the signal generator, measures power variations at the output
of the external signal path over a user-dened frequency range. The signal generator then
reads back the power level data from the power meter and creates a table of correction
values for each frequency point (the atness correction table). The atness correction table
is automatically stored in one of four non-volatile memory registers. Up to four atness
correction tables can be stored for later use.
When FLATNESS CORRECTION is on, the atness correction table adjusts the signal
generator output power (to comp ensate for losses or gains) to provide constantleveled p ower
at the external port.

To Use Previously Stored Flatness Correction Data
When the CALIBRATE FLATNESS CORRECTION routine is run, the signal generator
creates a table of correction values for each frequency point in the table. Up to four atness
correction tables can be stored in the signal generator memory. If the current signal path at
the signal generator output (the external signal path) is identical to the external signal path
for which a CALIBRATE FLATNESS CORRECTION routine has been run, the atness
correction table can b e recalled from memory and be used at a later time.
1.
Verify that the current external signal path is correct for the atness correction table that
you want to recall from memory and use.
The current external signal path must be identical to the external signal path that was
calibrated and stored in the atness correction table that you wish to recall. If the current
signal path is dierent, the data can cause inaccurate output amplitude s at the external
port.

If You Encounter a Problem
If you have a problem generating signals with the signal generator, check the following list
of commonly encountered problems and troublesho oting procedures. If the problem involves
data entry or the display,check the Chapter 2 section entitled \If You Encounter a Problem."
If the problem that you encounter is not in the following list or in Chapter 2, refer to the
Troubleshooting section of the
display module, or contact the nearest Hewlett-Packard oce for service.
If the UNLEVELED LED is on:
Check the leveled power specication to make sure that you have not exceeded the
specication.
Check that the ALC DIODE or ALC POWER METER functions are not inadvertently on.
