Page 11: General Information
General Information The HM5012/14 spectrum analyzer is easy to operate.The logical arrangement of the controls allows anyone to quickly become familiar with the operation of the instrument, however, experienced users are also advised to read through these instructions so that all functions are understood. -
Page 12: Safety
Safety This instrument has been designed and tested in accordance with IEC Publication 1010-1, Safety requirements for electrical equipment for measurement, control, and laboratory use. The CENELEC regulations EN 61010-1 correspond to this standard. It has left the factory in a safe condition. This instruction manual contains important information and warnings which have to be followed by the user to ensure safe operation and to retain the Spectrum Analyzer in a safe condition. -

Values without tolerances are typical for an average instrument. Warranty HAMEG warrants to its Customers that the products it manufactures and sells will be free from defects in materials and workmanship for a period of 3 years. This warranty shall not apply to any defect, failure or damage caused by improper use or inadequate maintenance and care. -

detected by this method. In the case of shipments by post, rail or carrier it is recommended that the original packing is carefully preserved. Transport damages and damage due to gross negligence are not covered by the waranty. In the case of a complaint, a label should be attached to the housing of the instrument which describes briefly the faults observed. -

The fuse(s) can then be replaced and pressed in until locked on both sides. Use of patched fuses or short-circuiting of the fuseholder is not permissible; HAMEG assumes no liability whatsoever for any damage caused as a result, and all warranty claims become null and void. -
Page 16: Operating Instructions
It is very important to read the paragraph “Safety” including the instructions prior to operating the HM5012/14. No special knowledge is necessary for the operation of the HM5012/14. The straightforward front panel layout and the limitation to basic functions guarantee efficient operation immediately. To ensure optimum operation of the instrument, some basic instructions need to be followed. -

(e.g. 1200MHz). The frequency range of 0Hz to 150kHz is not specified for the HM5012/14 spectrum analyzer. Spectral lines within this range would be displayed with incorrect amplitude. A particularly high intensity setting shall be avoided. The way signals are displayed on the spectrum analyzer typically allows for any signal to be recognized easily, even with low intensity. - Page 18 (2) INTENS: Beam intensity adjustment. (3) FOCUS: Beam sharpness adjustment. (4) TR: Trace Rotation - In spite of Mumetal-shielding of CRT, effects of earth’s magnetic field on the horizontal trace position cannot be completely avoided. A potentiometer accessible through an opening can be used for correction.
- Page 19 Remark: Functions AVERAGE and MAX.HLD cannot be part of a storage operation, meaning that SAVE cannot be performed if these functions are activated. An acoustic signal will alert the user in this case. Interrupt: If no instrument setting is to be saved the SAVE setting will automatically be deactivated after 3 sec.

The respective LED will light to show function is activated. Remark: The noise reduction (digital) using the AVERAGE function will not affect amplitude accuracy even for bigger spans, as would the video filter.
- Page 22 Remark: Is center frequency near lower end or SPAN increased, a spectral line might be visible, possibly even without a signal connected. It is commonly referred to as „Zero Frequency marking“ (ZERO Peak) and is not unusual to be seen in analyzers using the superhet principle.
- Page 23 Above illustration explains the terms SPAN, Center Frequency, Extent of Scale, and Attenuator. The gray area shows the maximum measuring range of the HM5012, whereby the white area shows the area which can be displayed on screen. The height of the „window“ is limited to 80dB due to the extent of the scale,...

- Page 25 (UNCAL display). In this case, SPAN needs to be reduced. With the aid of the Center Frequency (CENTER FREQ.) setting, first the signal to be tested needs to be centered on screen, then the SPAN can be reduced. If SPAN is reduced without the signal to be tested centered it is possible for the signal to end up outside of the screen.

(not included in HM5012) The TG output attenuator HM5014 has 5 positions,which can be chosen via the UP/DOWN-buttons. The output attenuator is used for reducing the output level of the Tracking Generator.

(28) Tracking Generator (not included in HM5012) After switching on the instrument, the Tracking generator will be inactive. This is a security measure to protect any loads connected. In the readout this is shown by the minuscule „t“. By pushing TRACK. - Page 28 ATTN. : As a protective measure the attenuation should be set to 40 dB (LED „40“ is lit). Frequency setting: Set CENTER FREQ. to 500 MHz (C500MHz) and choose a span of 1000 MHz. Bandwidth: For the first measurements the 400 MHz filter should be selected, and video filter off.

Obtaining values: For a numerical value of a measurement result the easiest way is the use of the marker. The marker frequency is set by the rotary dial, if necessary, use the fine step mode. Then, read the value for the amplitude, which is shown in the readout. -

displays voltage or power as a function of frequency on a CRT (cathode ray tube). In the time domain, all frequency components of a signal are seen summed together. In the frequency domain, complex signals (i.e. signals composed of more than one frequency) are separated into their frequency components, and the power level at each frequency is displayed. - Page 31 The swept-tuned analyzers are usually of the trf (tuned radio frequency) or superheterodyne type. A trf analyzer consists of a bandpass filter whose center frequency is tunable over a desired frequency range, a detector to produce vertical deflection on a CRT, and a horizontal scan generator used to synchronize the tuned frequency to the CRT horizontal deflection.

Page 32: Spectrum Analyzer Requirements
Spectrum Analyzer Requirements To accurately display the frequency and amplitude of a signal on a spectrum analyzer, the analyzer itself must be properly calibrated. A spectrum analyzer properly designed for accurate frequency and amplitude measurements has to satisfy many requirements: 1. -
Page 33: Sensitivity
Before the frequency of a signal can be measured on a spectrum analyzer it must first be resolved. Resolving a signal means distinguishing it from its nearest neighbours. The resolution of a spectrum analyzer is determined by its IF bandwidth. The IF bandwidth is usually the 3dB bandwidth of the IF filter. -
Page 34: Video Filtering
where: Noise power in watts Boltzmanns Constant (1.38 ⋅ 10 Joule/K) absolute temperature, K bandwidth of system in Hertz As seen from this equation, the noise level is directly proportio- nal to bandwidth. Therefore, a decade decrease in bandwidth results in a 10dB decrease in noise level and consequently 10dB better sensitivity. -
Page 35: Spectrum Analyzer Sensitivity
(increased by 3dB) because the signal power=average noise power. The maximum input level to the spectrum analyzer is the damage level or burn-out level of the input circuit. This is (for the HM5012/ 14) +10dBm for the input mixer and +20dBm for the input attenuator. -
Page 36: Frequency Response
determined from its specifications. First check the distortion spec. For example, this might be “all spurious products 70dB down for – 27dBm at the input mixer”. Then, determine that adequate sensitivity exists. For example, 70dB down from –27dBm is –97dB. This is the level we must be able to detect, and the bandwidth required for this sensitivity must not be too narrow or it will be useless. - Page 37 tuning since both are effectively tuned by the same VTO. This precision tracking exists in all analyzer scan modes. Thus, in full scan, the tracking generator output is a start-stop sweep, in zero scan the output is simply a CW signal. The tracking generator signal is generated by synthesizing and mixing two oscillators.

Furthermore the software package includes quasi peak and average calculations. In its operating mode ‘zero span’ the instrument acquires data over a period of 1 s, followed by the averaging of the data. Also, the quasi peak values are calculated by applying digital filter calculations. - Page 49 In the next step – for example - the frequency response of a component has to be defined.
